pretty much this:
2018-06-25 13:15:35,156 [9] DEBUG Logger - [TakeTransition] "Portal" has been successfully entered.
2018-06-25 13:15:35,198 [9] DEBUG Logger - [MoveTowards] Moving towards Dusk room at {1114, 1403} (distance: 893)
the portal takes the bot to the "Dusk room". but the next command is MoveTowards -> Dusk room. but we are already there.
EDIT: if i move around a little bit in the boss room and then hit "start" again, everything is fine again. but i need to move around a little bit before hitting start again. i hope this information helps. i encountered this problem several times now.
