Will write here as well as in the bug report. I've been stuck at the choclate factory maze up to this point for a bug, that was apparently signal before as well, about the supposed timer that has been set for the 2 levers' floor. As this point in time, it is impossible to complete that floor whatever time it may tae the player.
A suggestion to solve the issue might also be a change from a timer to a check in the player's weight, where if it crosses a certain number (or level) it trigger the specail event.
