In the latest two verions of the mod, I have been running into the error below, after playing for a long time...
It seems like its related to the amount of time the colonist have been with the colony/ingame.
As the bug can be "fixed" by killing off the colonist. Then after a short while it will happen to the next colonist that joined.
I currently use the SK Global Modpack 1.8c, with the exception of the seeds please mod.
Note: The bug seems to be related to the bug where rendering fires would cause problems, so may be a A11 bug not related to the mod, still hope that someone got a solution

Exception drawing Fischer: System.IndexOutOfRangeException: Array index is out of range.

Edit:
Tried to figure out what was causing the problem and played around with the savegame data.
"Fixed" the problem, by editing out some missing bodyparts from the pawn. This fixed the issue for now.
Look like the issue may be related to adding to many implants to the pawn, this cause a lot of missing bodyparts (not shown in game, but still shown in save data), as example a leg will remove foot and toes.
Not sure if the out of range exception is related to the whole pawn or just the list of surgeries.
Example of data removed.
