Colonists are "Standing" and will not do work.

[Mehni]

I noticed a lot of my colonists suddenly going idle - except they were just "Standing" and wouldn't seek any work. I could draft them, order them to move, and sometimes they would go about their day again. It wouldn't be long before they returned to their zombie statue of "Standing". Wardens might be affected as well, I haven't tested that out.

Reproduction:
1) Wall in all your drugs, so the junkie on a binge can't overdose on Go-Juice. Be sure to also wall in your herbal medicine.
2) Schedule a prisoner to receive a peg leg.
3) Your doctors will try to operate on the poor hapless/legless prisoner, but instead they stand around as zombies.

Here's a linked savefile.

Could you upload a copy of the "output_log" file?

Log File
Posting a log file means uploading the log RimWorld generated. Here's where to find it:
Windows (Steam): C:\Program Files (x86)\Steam\steamapps\common\RimWorld\RimWorldWin_Data\output_log.txt
Windows (non-Steam): RimWorld####Win\RimWorld####Win_Data\output_log.txt
Mac (Steam): Users/<UserName>/Library/Logs/Unity/Player.log
Mac (non-Steam): /Users/[your user name]/Library/Logs/Unity/Player.log
Linux (Steam): /home/<UserName>/.config/unity3d/Ludeon Studios/RimWorld/Player.log
Note: You must run RimWorld from the console or the log file will not be created.  If you don't run RimWorld from the console, you may find the log at /tmp/rimworld_log
Linux (non-Steam): /home/[your user name]/.config/unity3d/Ludeon Studios/RimWorld/Player.log
