Unfortunately, the walking bug compromises my game again. At least I’ve finished that cut-scene. For everyone of you, who also are struggling with that bug:
To initialize a cut-scene with the “hero walks towards”-command instead of the “hero walks to”-command helps a little to have the hero at least after that command in the right position. However, the player keeps control of the hero and therefore still is able to accidentally or indended destroy your cut-scene afterwards.
