Creature banks.

 

The advice helped, thank you. But there's one problem. In single-player, the scripts work, and the treasure chests function as they should, but this doesn't apply to multiplayer. When attempting to start a game on an RMX map with an opponent, all creature banks reset their scripts and function according to their original functions before the changes. When attempting to play the same map in single-player mode, everything works as it should again. Of course, the opponent also has the modification installed. What could be the problem?
