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) has TWO possible locations:
RimWorld####Win\RimWorld####Win_Data\output_log.txt
%userprofile%\AppData\LocalLow\Ludeon Studios\RimWorld by Ludeon Studios\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
