Yea, there's a skybox brush there that apparently ate that top section of that building (which is func_detail). I'll have to nodraw it instead.
As for the "floating" roof, it's attatched to walls on 3 sides, and with a thick support beam running through the middle (which isn't that visible), it's not that different to the space outside 2fort's main spawn. If it's really that out of place and i get more comments on that aesthetic, i'll see what i can do to make it look more natural.
I'll really concentrate on the visuals when this goes beta, hopefully this will be the last alpha. The cooldown mechanic doesn't seem to be working though, in that the teleporter function with the "hidden room" is still being bypassed for some reason. I might need a little help with that.
