My project crashes on load

I’ve submitted countless bug reports through your tool -

When I load my project I get the following crash

below are two crash reports - the second one is if I rename a usasset file - it somehow tricks it so it can load - however if i save - it crashed with the limited repot

This has been happening in 4.2 – I’ve been waiting for 4.3 to resolve this - however it still happens in 4.3 preview

HI BPANDREW -

Thank you for your report. I will begin investigation into this issue as soon as possible. Can you give me a run down of the nature of the project that is causing this problem and exactly what you were editing immediately before the crashes began?

In the meantime, please be sure to review our suggestions for how to report a bug, and feel free to edit your post if you have additional information to provide:

Thank you.

Eric Ketchum

Hi Eric - it seems to be related to the fact that make pretty heavy usage of inheritance - i finally got the same “access denied” that was stopping me before (i was forced to revert to an older build but its come back again)

Hey BPANDREW -

Looking over your crash reports, it looks like the assertion failure occurs with a Blueprint, or code, that calls and generates a Child Actor and sets its transform. I have tried to reproduce this error and so far have been unsuccessful.

Some questions to eliminate some possible errors, have you done any of the following before your crash occurred:

-Copying nodes from a macro and removing the macro
-Collapsing macro nodes together that are in each others graphs

Thank You -

Eric Ketchum

I have not worked with macros - i assume those are your prebuilt blueprints?

I have however worked with the behavior tree system, which i reverted

I have a base class for my ships, and then my ships have child actors in them for the weapons that are installed in them - which itself is a base class - perhaps that is it.

I changed my weapon base class and got this just now

We apologize for the inconvenience.
Please send this crash report to help improve our software.

Hey BPANDREW -

I traced your crash to a known issue with changing a parent blueprint and then a child blueprint and then the parent blueprint again. Our engineers are currently work on it and I will let you know as soon as we track down a fix.

Thank You

Eric Ketchum

just tried it in 4.3.1 and no good - is this fix going to take a while? I’ve been having major issues since 4.2 - maybe I should unsubscribe until then

I’m still having this issue in 4.4 preview - my project wont load at all

access violation

I get I’ve probably done something wrong - this is however the second time I’ve pained myself into this corner and I have no idea what I did wrong.

loading my previous version that works in 4.4 - i get some warnings on play in editor

"Error Internal compiler error inside CreateExecutionSchedule (site 1); please contact the framework team as we need a repro for this bug!
"

Hey BPANDREW -

Wow ok, can you upload your project? I would need the *.uproject file, and the following sub directories: Config, Content, Source (if used)? If you need a private place to upload the project please let me know and we can arrange something.

Thank You

Eric Ketchum

I’m having this issue again - i created a new project and didnt use any sort of inheritance

i was having a issue saving my controller/hud class and it was saying something about a hidden reference and wouldn’t save. exited out - wont load my project again

i should also mention im using github for my project, perhaps thats creating some sort of file access issue?

Hey BPANDREW -

Are you adding or altering any code form the project or are you adding any code to a project or are you merely pulling the engine down from GitHub?

Thank You

Eric Ketchum

i’ve been using your launcher to download official builds - i however store my project on github

my current issue is with 4.3.1

yes - however one of my projects was blueprint only - but yes thats my scenario

I’ve hit this dead end 3 times now with projects created in 4.1x, 4.2x and 4.3x - my last iteration was based from the 3rd person template, ive used no OO or composition

the actions i did this morning - i did migrate some particle systems from the 3rd person template. however this “unknown reference” to my HUD/controller (i forgot) started happening a few days ago

i’ve submitted a few reports today - sorry about my tone, this really gets me frustrated when i lose work

Hey -

So you are downloading the engine from the launcher creating a C++ project and storing the source on GitHub or the source and Content on GitHub? I want to confirm.

Thank You

Eric Ketchum

see attached

“graph is linked to external private object”
“graph is linked to object(s) in external map”

i sorted this issue out - my hud was referencing a blueprint library that had a common “draw button” method - i deleted the calls to that and this issue went away and my blueprint was able to save fine

this was created because I had a common UI theme amongst different maps - yes I can probably get rid of that with upcoming UMG - but i had to process of elimination delete methods from my hud class to figure this out

sorry - that HUD issue didnt seem to be the cause of my project load crash - i placed the fixed hud in my crashed directory and that didnt fix it (i even deleted out the uassets and it still wouldnt load)

checking my log this seems to be the biggest error - i will post the whole log link text
