AGS: MMM - Episode 8 hangs at the final cutscene

[NuclearNemo]

This report is about a freeware AGS mini game (MMM - Episode 8) that can be downloaded here:
​https://www.maniac-mansion-mania.com/index.php/en/spiele/episoden/staffel-1/26-episode-8-die-abfuhr.html

The final cut scene at the end of the game hangs/aborts and the game can't be completed.

How to reproduce:

• Start game
• Load attached saved game
• Use recorder with cassette
• Go to the kitchen (go through room door, then always keep left)
• Open window
• Use recorder with record on it with open window

Then watch the cutscene. After Klaus goes to the garden, Bernard tries to get back to the trap, but just stops at the door and stays there forever (see attached screenshot), so the cutscene is basically aborted. (If you click left, the mouse cursor becomes visible and you can walk through the house, but you can't end the game since the game is intended to end after that cutscene.)

Fixed. It seems to be a problem in the stand-alone version as well. The MoveChracterBlocking method is currently a void return, but the game script expects it to be an int that returns a non-zero value if it completes. Since no other games should (I presume) expect any return value, it was a simple fix to change the method to return 1.
