Game crashes when a massive number of units are on the field at the same time

OS: Windows 10 Game Version: 1.15.5

Game crashes when a huge number of units are on the field at the same time, no matter what. I couldn't find a dump file or a log file to lookup the issue, and the only thing that the game displays it's a segfault (when run from the command line).

Also, searching for a way to enable the debug mode or at least try to log anything, I found out that there is no wiki about how to achieve this but the Error Class page which tells in a vague way to set an env var (SKDEBUG) to start debugging using channels but no further documentation can be found about what channels are defined in the wiki neither in the code itself.

If you have a save file, and explain how to trigger the issue, send the save file and I can check the crash.

It's a long shot, but I recently saw a crash that is related to action code. That is a lot of units, so the trigger situation can increase in probability.

Hello sebaro. This crash you have is caused from a bug earlier in time in your game, leaving a corruption on the map. Unfortunately the save file was created after the corruption occurred. So I cannot find the root cause. However, I have fixed bugs that have caused these kinds of situations, so hopefully the next version will have fixed this.

The issue here is not likely due to the number of units. There have been bugs fixed that are related to this sort of problem. Please go here and get a recent dev build and check the stability: https://7kfans.com/forums/viewtopic.php?f=20&t=1290
