Sinon ils évoquent sur le forum officiel un bug lié à la police du jeu:
"Windows font crash (frequent crashes during gameplay/starting game)
This is a rare Unity engine bug caused by a Windows font the engine is incompatible with being installed on your system. It can be fixed quite easily by following the steps below to delete the font file.
- Turn on display of hidden files in Windows: http://www.bleepingcomputer.com/tutorials/show-hidden-files-in-windows-7/ (be sure you have selected both "Show hidden files" as well as unchecked "Hide protected operating system files")
- Navigate to C:\Windows\Fonts
- Delete the file UNCLL.tff
If you have trouble with that method you can also try:
- Go to Start -> cmd.exe -> right-click, Run As Administrator
- Type in "cd C:\Windows\Fonts", press Enter
- Type in "del UNCLL.tff", press Enter
That should get you up and running again."
