Just updated my project to 4.18 and when I package and run it under a non-shipping configuration I get the following error when it tries to load one of my maps:
We have a main menu and a cutscene that happen before loading the map this happens in. This does not occur if my configuration is “Shipping”, only “DebugGame” or “Development”.
I reverted to 4.17 and don’t encounter this error. I use the following settings when I package:
I’ll be looking into this but before I can do so, can you provide log files from the packaging process for Development and Shipping so that I can try to spot any considerable differences? Also, as a possible temporary workaround, can you try disabling EDL (Event Driven Loading) to see if you either get another error or if it allows you to launch a development build?
Here are my development and shipping logs. Disabling EDL did allow the level that was causing problems to load, so at least I’m now able to debug my builds. Thanks.
If I turn Generate Chunks off and EDL on I don’t encounter this error. I originally turned Generate Chunks on because we had enough content it caused 32-bit builds to crash (>2GB I think is the limit) but that doesn’t seem to be happening anymore.
While testing this I found that the error was no longer happening, I had to revert to last Friday’s build. It looks like it stopped happening after we modified/saved the map that was failing to load so that’s at least an easy fix on our end if you can’t work this out on the engine side.
Without having a reproduction case of some sort, we can’t focus on making a fix as we cannot determine if we have fixed it. As this isn’t happening any more, I’m going to my last comment to an answer. If you do experience this again please let me know. If you can find a way to reproduce this, that would be even better.
