Hi, i checked google & first 5 pages and haven't found anything like this.
So my problem is im at burrowers nest (in GMS compound) I threw molotov (so the ground is on fire) left the location to heal & CD, going back to nest (and here sometimes my autosave is corrupted, can't load it) but if i manage to get back to nest (by saving on another save) i crash when i throw "second molotov" (second, because previous one was thrown and is still burning). IDK but it seems the problem is i left the location with burning ground and burrowers in it (just my thoughts).
Also - i dont get XP for killed burrowers (or spawns) by fire ground, IDK is it intented.
But i love your game, just love it.
Hope it will be fine, got a savegame in case you want,
thanks!
