This one is quite easy to reproduce.

Starting a level, as a host if you open the first door of the dungeon while other players haven't appeared yet, there will be a problem with resources.

Players appearing after the door is open will have less ressources and less dust (if there was dust behind the first door).

The result will be a glitch where players with less dust won't be able to light on a new room.



To avoid this make sure everyone is with you when you open the first door.
