Do not use trapdoors or doors in boss walls

Something I've noticed during my many, many attempts at defeating Tasim is that I'm often unfairly hindered by the mechanics of the walls. If I'm right next to a wall and trying to Teleport, I can't, because trapdoor and door blocks are weird and I may be misdetected as inside one. I can accidentally open the trapdoors and doors, creating unintended obstructions and interfering with spell inputs. The obvious solution is to just use regular wood blocks. I don't see why this wasn't done originally.

I can't remember other similar incidents in other fights, but it's possible there were some of these. It's most noticeable for me against Tasim because his arena is strangely small and I attempt him a lot.

 

The number of Fruman windows I can't teleport through because there's trapdoors in them is almost as high as my blood pressure when I try to.

 

The number of Fruman passageways that should lead somewhere that just vantablock...

Say, did you know the train in Fort Torann is non-Euclidean? The tunnel under Torann's other side is actually a regular old room, so if you plow a train through that direction you actually slip into an alternate dimension. I'm told Majin was involved.
