Had a glitch were doors would open the moment I gave the hero the command to open them, before the hero moved there. The hero would afterwards run to and through the door. This movement could not be canceled. It would mean that the hero would run through the waves of incomming monsters and then would have to run back.

It happened on the first necrophage level.

Sadly don't have any more info to give.

Summary: the actions for opening the door happened in wrong order: door opens then hero moves to door.
