I see you have a number of mods loaded. Have you checked that are all updated to work with the latest game patch?

If you start a new test colony with no mods enabled, does this problem still happen?

Can everyone please at least attach their game log files here, preferably the affected save game too?

And have you all checked for mods being up to date?
