Well, I was under the impression that a semisolid brush, like a crate in a room doesn't cut up the BSP -- the crate sits on the floor and the floor poly remains a single poly, if you ghost into the crate you can still see the floor.
However, while editing I managed to get this BSP: the stair brush is a semisolid, rotated by 45 degrees, and it's produced a cut in the floor of the room its in.
There's nothing else in the level that has a poly coplanar with that cut -- hence I can only concluded that the semisolid stairs are responsible. weird huh!
Am I wrong about semisolids or have I made a mistake here, or (shock horror) do we have to re-examne our theories on semisolids? This could be big news for Theoretical Unrealologists!! :D

When I was fiddling with my office tower staircase, I'm pretty sure that my semi-solid stairs could cut up the BSP on the walls in the stairwell.

I didn't have enuf time to look into it, but I think someone said that this could happen under certain conditions during the geo optimization phase.

When I was building the stairs, I messed around with a LOT of different techniques, and almost every time I had my stairs touch the wall, I got BSP cuts up the yingyang. In the end, I kept the stairs from touching the walls so the walls didn't get cut up.

It mostly happens when you add the semisolid next to the wall. If you add into an empty space, rebuild, align, rebuild...it probably gets fixed. Try doing this to the solidity too. Stairs can do weird things because of the great density of polys. Also try merging polys.
