Factorio version: 1.1.87
Rampant version: 3.3.3
Map evolution: 0.75 (hard capped manually)
rampant was present since the start of the game
randomly while playing on the map, the game stops and shows a message with the text as above, forcing the player to return to main menu without being able to save or recover
the map now has roughly 180h and it hasn't done this all these hours before. Updating the mods, respawning the biters, killing the biters, deleting chunks all did not fix the issue.
at some point in time (roughly before it started) i removed the wasp spitter faction. after that it started causing this issue. however adding them back did not change anything. help would be greatly appreciated.
