Hi Maximini, I'm sorry to hear that. Do you have any more information so I can try and track down the bug? An error.txt file would be best. Also, have you tried to close the game and re-open your save?
That's fine, I solved the issue by just walking around the world to cycle things. Next day was fine. I can say it was triggered by using the bed in Ordon.
My error.txt is about something else
[Solarus] [2618890] Error: Missing treasure dialog: '_treasure.poe_soul.1'
(most likely related to poes in the Subrosian shop) (which happened before that bug).
I tried save and quit and closing the whole thing and rebooting, without change.
I would also report another bug in dungeon 4, in the far-left room on first floor, if you push the blocks against the north wall, they get displaced by an half-tile and it's totally impossible to push the buttons without going out the dungeon to reset them.
