Hi there, sorry if this is the wrong place for it. I started up a map in 0.15.11 and disabled biter expansion and evolution, but it later appeared to have changed the settings when i updated to 0.15.12, as the biters were expanding as do in a default settings game. The console also says that their evolution is progressing. I'm not sure how i could recreate this though.

Post the save please.

sorry about that

Thanks for report, though simple repro didn't work. I started a new map in 0.15.11 with evolution/expansion disabled, then I was standing still with game speed of 1000 for a couple of seconds, checked that evolution did not grow. Then loaded this save with 0.15.12, waited for another thousands of ticks - still nothing, evolution is standing still at 0.0. Something pollution-related could probably be a migration issue between those versions, but there is high probability that something else triggered this change or that this problem is relevant only for past 0.15.11 migrations. So until we get more reports of that type, moving to Won't fix.
