Hopefully someone can assist; the game has suddenly started coming up with an error box as soon as I try to zone 'cell' rooms. It doesn't matter how I do it, or what prison I try it with. This error box then persistently reappears, making the game unplayable pretty quickly.
Any advice anyone, please?
The error box is titled 'Fatal Error' and states:
Assertion failed: 'shadow[index]!=0'
line number 218
