The door/ladder down to where the cages are is undetectable and could not be found both by our group and with a DM helping. This makes getting the people who fell into the floor quite hard. =P

Also, the collapsing rocks below seem to be weird in that you can run through them sometimes, and other times cause them to fall? They are also quite buggy in that it is easy to become stuck in the rock object once it is down.

My group did not explore any further than this, so if any bugs exist in the final room then I do not know about them.

The "Search" function is such an useful thing, although long forgotten :P

On my to do list.

I suspect the falling rock traps may still have issues, but the secret door downward has been changed from a DC 28 (!) to something much lower.
