Fixes, that the robbery scene in Blue Ville happens multiple times (should only happen once of course).
If the bug already happened to you, please revert to a backup savegame; this is how:

Savegames are stored in:
C:\Users\<yourname>\AppData\Local\Supraland\Saved\SaveGames
(Appdata is an invisible folder, you need to set windows to show hidden objects)
There is a backup save every 15 minutes. To use them rename them to something between save1 and save5. The number defines the slot it will be in. There is no need to change the "slot" files.
