Huge Productivty Bug in BP ~ "Graph is Linked to Object in External Map"

Dear Friends at Epic,

Myself and my team are encountering huge productivity issues in blueprints with the following error:

It is easy to reproduce by making an AI Controller BP and then trying to use the Stop Movement node, and then saving the blueprint

It causes this error to crop every time for me.

Sometimes closing and reopening the editor gets rid of this error

but once it starts, there is no way to get rid of this message without closing the editor and losing progress.

Other times I have no solution but to remake the entire asset where this error crops up and it is A HUGE PROBLEM.

I am finding this extremely irritating, please take this matter very seriously.

It is costing me a lot of time.

It also means I am literally afraid to use the Stop Movement node!

Please fix this!

#Context

I am just editing a single map and blueprints, and running PIE periodically, always on the same single map

it is the only map I ever load.

#Update

This error of being linked to external objects has one again reared up

but this time, it is stopping me from packaging Solus!

#Error

Hi Rama,

I just ran a quick test in 4.1.1 and 4.2 and I am able to create a blueprint on AIController and have Stop Movement node without any issues, no matter how many times I open the blueprint, restarting the editor and opening the blueprint again never causes any issues. I believe the issue your having may be somewhere else in the blueprint, but when placing the Stop Movement node is causing the issue to come to the surface. It may help everyone if you show more of your blueprint (If you can). And also does this happen in a brand new project with the bare minimum ie. An AIController with Stop Movement node, or is it just in your project.

That’s great research thanks for the help Ehamloptiran!

I will check out Stop Movement in a new project soon.

Epic if you have any more info about the nature of the error message please do let me know so I can see how it might be project specific :slight_smile:

Rama

Hi Rama -

This error usually occurs when something is either set to have a class specifier of Transient or is the child of something that has this setting.

I have had this error crop up when I copy and paste nodes from one blueprint or material into another without attempting to connect the pins internal to the new blueprint. I am not saying that this is you issue here, but if you have done any copy and pasting into the blueprint with this issue that would be where I would begin tracking the error down. In particular since Stop Movement is the node where the issue is cropping up, I would look for any nodes which reference player movement or AI movement which might be referencing a Transient class.

I will continue trying to track down this bug in more detail, but hopefully this information can give you a place to begin -

Thank You

Eric Ketchum

Dear Eric,

I have never seen this error before 4.2, and I’ve been using UE4 since Rocket Beta3.

But I"ve seen it crop up now in several different projects!

I am not sure why it is cropping up more often, as the situations where I encounter the error are wildly different.

In my latest case I had a blueprint which had dependencies to about 10 other blueprints.

I was also modifying my level .umap

So when I went to save, it wanted to save the blueprint, and all its dependencies, and the .umap

I could not save the .umap, the same error popped up which this thread is focused on, which canceled the save process.

I had to manually unclick the saving of the .umap, and then save it by itself after all the other blueprints finished

Again I’ve never seen this error before 4.2!

Just putting more info out to you for your research.

Thanks for looking into this Eric!

Rama

Hey Rama -

With the Blueprint that is generating this error can you (from the content browser) take a screenshot of the reference viewer of the blueprint (right-click >> reference viewer)

Thank You

Eric Ketchum

I can’t take a screen shot that you’d be able to read because the reference viewer is too densely packed, even with a depth of just 1

Please see my updated original post, as I now have a packaging log to go with this error, and this error is stopping me from packaging Solus!

Let me know what you’d like me to do!

Here is a picture of the asset in ref viewer, as you can see it is used in a lot of places :slight_smile:

will you need a download of the Solus project to help us debug this?

I have no idea where the “Unkown” reference is!

Rama

Hey Rama -

Can you send me the *.uasset for the offending BP? I am sure this error is in relation to how a reference is called but without being able to look at the whole logic I cannot narrow it down.

Thank You

Eric Ketchum

#Asset for you Eric!

It was too big to attach so I am hosting it on my private server, please do let me know when you are done downloading it :slight_smile:

http://lightningfitness.org/misc/video/SolusPlayer.uasset

Have fun today Eric!

Rama

Hey Rama -

Can you give us the output log file? Also I was able to see the Reference View of your *.uasset but it is referencing so much code and class that I do not having access to that I cannot open it directly. The project’s output log files from the project especially from when this error occurs would help us narrow this down.

Thanks Rama

Eric Ketchum

Dear Eric,

Here is the entire log!

It is 7mb uncompressed, it is attached!

Hey Rama -

Thank You for your logs with them I was able to trace the problem to an error in the blueprints which the logs are throwing up as warnings. Unfortunately without a complete copy of your scripts and blueprints I have no directly way to debug the issue from here. I can say the issue resolves around the blueprint trying to save or call an action, event or variable that hasn’t be substantiated yet and anytime you do that you will get the warning you first reported.

Thank You

Eric Ketchum

Okay thanks for doing that research Eric!

I will keep you posted on how this all goes!

:slight_smile:

Rama

Just had the same problem, is there a fix for this? I wasn’t using the Stop Movement block. I have no clue what caused it, had to redo the whole blueprint and it worked fine.

I found the solution recently, you just do a BP search for the word transient and delete and replace all nodes that had it

Rama

Nooooo - this does not work - ‘transient’ is not found!!
