Colission issues

Did not happen to me but I stumbled upon this picture. Seems like there are phantom BSPs(Just like in the good ol’ Halo CE days). I don’t know if it’s caused by the default map itself or by the intersecting forge pieces. Probably the latter.

Wow, so the Forge maps are broken to minor extents like this? Does this mean custom maps made in Forge are gonna suffer the same fate?
