Random traceback

[ghost]

So I left the mod in the background, got to do my own business and stuff, and when I opened it after some time it greeted me with that.

I'm sorry, but an uncaught exception occurred.

While running game code:
  File "game/script-ch30.rpy", line 1427, in script call
  File "game/script-ch30.rpy", line 1596, in script
  File "game/script-ch30.rpy", line 1620, in <module>
  File "game/zz_windowreacts.rpy", line 217, in mas_checkForWindowReacts
  File "game/zz_windowreacts.rpy", line 191, in mas_isInActiveWindow
  File "game/zz_windowreacts.rpy", line 156, in mas_getActiveWindow
CalledProcessError: Command '[u'xdotool', u'getwindowfocus', u'getwindowname']' returned non-zero exit status 1

Seems pretty much like something related to window reactions?

[Booplicate]

Fixed in #6014, you'll have to disable window reactions 'til next release.

Roger that.
