During my playthrough I've encounered a bug where large groups of frozen/inactive biters gather at the sides of a nest, or elsewhere randomly in the world.
Around the same time I've noticed this happening, I've also noticed that the biters have stopped coming to the Administration Desk alltogether. As the result, I've not been able to get any biter workers. I'm not sure if this is related to the first bug. I don't know what has caused this, I haven't had time to try to replicate these bugs.

Here is a Google Drive link to the save file and some screenshots: https://drive.google.com/drive/folders/1TJu2wgIn_Mer07vb_YRg08N8rDtK_D6t

Is there any way of fixing this without running any console commands? I'd like to still be able to get achievements.

Besides this, great mod! :)

Hey glaazo, thanks for the bug report ! It was a bug that I introduced when trying to address biters despawning too early, I guess I went too far haha !
Anyway I addressed it in 0.5.2, loading your save should despawn all the bugged biters and resume normal behavior of the mod, no commands ! :)

Thanks for your report and the attached map, it helps me very much, so glad you like the mod don't hesitate to give me more feedback / bugs

Wonderful, all fixed now! Thank you so much! :)

Oops, I think I spoke too soon....
When I first loaded the game after updating the mod, the frozen biters disappeared and started going to the Administration Desk again (and even spitters started spawning!), but then 15 minutes later I saw that they started doing same things again.

Here is the new save and screenshots: https://drive.google.com/drive/folders/1fHIFsdENXZsUc3t_e0ahoiNKBccGTqN4

Let me know if there is anything else I could help with :)

Uuuuugh the issue is even deeper than that, well sorry about this, I'll continue investigating

Ok I think I got it this time, I let your save run for multiple minutes and it seems to be addressed, let me know if you still see issues in 0.5.3 ! :)

I've ran the game for about an hour with some heavy research and complaint resolution, all seems to be working well now!
Thank you so much for your efforts and lightning fast fixes! :)
