Hey all, i just made a simple 2 room map, with one room as a semi circle that has the floor and cealing capped to fit into the semi cirle, and the other room as a square. when i go to compile my map it says map leaked and when i follow the red line to see where the leak is, the line never leaves the room. in fact it just seems to circle the room then just stop. i am 100% sure it does not go outside the rooms, what does this mean and how do i fix it?

Make sure that none of the curved surfaces touch the void, as they are ignored by the vis process. Put a box around the dome instead.
