I have a few maps that use mm_17housebuild. The players messaged me that the map has invisible barriers now. Which I didn't remember adding any. I looked at the map, I found that the blocking mesh must have changed on mm_17housebuild. I can no longer walk through it if it is enlarged. Before the windows didn't have collision. I'll change my maps I guess but it would be nice for that collision mesh to be put back.
