Hi, are you going back to a save you made before getting the ending? Did you make the save in the kitchen before or after the exit opens? If before, you might just need to interact with the cooker again to get the exit to open up. If you saved after the exit was already open then it is possible this is a bug - I'll need to check it and see
Hi, I've just tested getting ending B and then loading my game, when I loaded the hole was blocked again but after I interacted with it it opened up again so I could proceed - did you try interacting with it? If you did and still weren't able to proceed, could you email me at graystargamestudio@gmail.com with some more detail so I can try again to replicate the bug?
Thank you :)
