( Warning: Secret spoiler! )

When you get to the platform that unlocks the secret door, you can hear the grinding sound of stone, as the door unlocks, but you cannot click it to access it, you can walk into and beyond the opening. It is also hard to get to the other secret because you have to guess where to navigate as the path is covered up.

This dungeon previously spawned in a right orientation so I know exactly how the secret is suppose to work  

See screenshots for a clearer idea of the issue.
