Locking thread. Since a workaround was already posted above, as was the instructions to submit a SUPPORT TICKET should the workaround NOT work, there's nothing more anyone here on the Player Forum can do.
**WORKAROUND if Peter HAS NOT Yet Been Freed: **
When u come to the room, continue forward and get into the door on the top. as soon as you reach there, take 1 step forward. Robin and all will follow u there. DO NOT DO ANYTHING and come back. When you come back, the path will be open and you can clear the tiles.
If you FREE Pete, then Robin blocks the 3 tiles and you cannot do anything about it except submit a ticket.
Click the button under the game settings wheel, upper corner of the game window. Once on the linked page, scroll PAST the white search 🔍 box & choose a category to begin the form. If no category options are listed, email SUPPORT instead: firstname.lastname@example.org
Include your Player ID, found under the game settings.
Any updates on a fix from Pixel will be relayed in the Events section of the Forum.
