Crash: Loading a new level from the editor "(level) still around trying to load"

What could be causing this crash?
That says this aboug “still around trying to load”.

Fatal error: [File:D:\BuildFarm\buildmachine_++depot+UE4-Releases+4.6\Engine\Source\Editor\UnrealEd\Private\EditorServer.cpp] [Line: 1721]
//Game//Maps//level00_mainmenu.level00_mainmenu still around trying to load F://_pxUnreal//Projects//Bolicaco//u

My project is currently working fine, every level open and run ok individually, but many times when I have one level openen already on the editor and I try to open another one to edit… then crash.

If open again the editor and upload the desired level it works ok for while until the next crash.

UPDATE: Logs crash dumps

Hey -

Does the crash happen when opening any level while another level is already open or does it only happen when loading a certain level or with a certain level already open? Have you had the same thing happen in any other projects with multiple levels? Also, are you opening the level by double clicking on the level icon in the content browser or are you using File->Open Level? In your projects Saved->Logs folder, could you send us a zip of your log and dump files from when the crash occurred.

Cheers

Hi , thanks for replying. I have updated the question with log files.

It happens randomly loading any level after some time working with blueprints, editing level, and playing in editor.

I can’t reproduce the crash with other projects, tested with Content Examples and didn’t crashed.

The crash happens no matter what path I use to open it.

When I load my project the first time, I can open other level without crashes.

The game never crashes when switching levels at run-time.

A superstitious issue that I can’t find the way to fix is when I open my project always the Output Log show some event “compiling” errors in red text, but my game runs perfectly. Image attached.

Thanks for your help. Happy new year!!

Just wanted to say that I’m getting this same error. I can work around it by editing the level to load on opening the project, but it’s still a pain!

Yes, I have to live with that pain, crash, reopen, crash, reopen…
Btw, you should put your message as a comment not an answer :wink:

Thanks. I haven’t really used answer hub before, so sorry for getting your hopes up!

Update: I managed to remove the red text error of out put log when loading the project. Seems like that happen when you try to bind to events of spawned objects. It works weell but when loading compiler get confused.

The crash still remains.

The crash occurs after I modify any blueprint, if I try to load a new map.

When editing maps only without modifying blueprints I can open different maps without crashing.

(Happy new year)

Hi!
Yes, the crash occurs after a few minutes of modifying blueprints, compiling saving and running the game in PIE, can be sure the order, or which specific blueprint is the problematic.
What I’m sure is that if I edit my levels or create new ones without modifying my blueprints then the crash never happens.
A new recent update: I noticed that I have disabled level streaming on project settings before, then I re-enable it and for some time the crashes disappears, but later working again with my project the crash returned :frowning: can’t say if in minor frequency I have to start working on it today again to know.

Sure, I’ll send you my project files.

thanks

Hey -

I still have not been able to reproduce the crash yet. Just to make sure I understand, you’re saying that the crash only occurs after editing one of the blueprints in the project? Would you be able to send us your project to test directly? If you are able to upload the project to dropbox you can send me a private message on the forums with a link.

Hey ! How I find your forum user?

Almost 100% sure that the problem is when I left blueprints tabs opened in my editor layout. If I close the tabs before opening a new level the crash doesn’t happen. So, anyone with this problem, try to close all tabs and tools before changing loading new level.

Hi ,
I think the crash occurs only when I left blueprint tabs opened. If I close all tabs before changing the level I don’t get crashes. Still I need to try it several times to be 100% sure.
regards

Hi, try to close all tabs and windows before changing the level, most crashes disappeared.

Hey -

I have been using the project you sent me and have not had any luck in reproducing the crash however I have made a note of it in our internal tracking system. It sounds as though you have found a working solution to the crash. I will be marking this post as resolved for the time being. If this problem occurs again let us know with any addition information and we will re-investigate the problem.

Cheers

Hi ,
Thanks a lot for the help.

I’m getting this now loading one specific umap out of many (others seem to work). This is after moving too 4.9 Preview 3.

I don’t have any blueprint tabs open.

It’s not quite 100% - perhaps 80%.

UE4Editor.exe has triggered a breakpoint.

“Fixed” by duplicating, replacing references to the original etc.

Though now (Preview 4) it seems like other levels are doing the same thing… PITA!

And this time the duplicate and re-reference trick doesn’t work.

Hey -

Could you provide the log files from the crash you’re getting? Does this reproduce for you in a new project created in the 4.9 preview? Have you tried using 's solution of making sure that other editor tabs (blueprints, material editor, etc.) are closed before switching levels?

Cheers
