Yeah I have the same problem, luckily I have gathered all seven together, before scrying room locked up, but I am now trying to cure the transformed animals and cant get into the basement cos the picture doesnt work and the wall is sealed again.

Sigh.

I keep finding new treasure though, but the monsters havent respawned :-(, I found the strange amulet again.... but it is rather worrying that I am going to bump into something else I can't do.
