One More Block

So, you know that some block sets have the Corner Pipe piece?

(this one)

I've made a little test map to demonstrate my issue.



Perfectly fine, right? Well, when I place the corner pipe, this happens...



All the level geometry is still intact, just invisible.

When I delete the corner pipe piece, everything goes back to normal.
Does anyone know why this happens, or how I can fix this?

I have the same problem !!!!

Same here, but I guess the devs can't do much about it right now...
