Game entity update suddenly grown from ~8 ms to 60 ms.
Fps dropped from 60 to ~16.

I have both saves, before and after.
On my PC the bug can be reproduced if to load the old save and wait for like 10-15 minutes.

Hello, there is certainly a big bug, that the air filtering mod change the evolution factor to be -20000.

I fixed that for 0.12.9.

You can use this command to make the game playable again for you now.

Thanks.
