When attempting to access the secret room in Anephas' by pushing the stone guardian (on the left) down the passageway, it continuously gets stuck. Does this happen to anyone else? Is this a bug? I can access the secret room on the right, however, this is driving me nuts. Any help appreciated!!!

I haven't tried pushing it... instead I pulled them out of the wall.... And I found no problems in doing that....
Maybe that's what you need to do.

Hope this helps!!
