I had a simple map. Basically a room, with decorations (pillars, niches, the like). I added a small hallway with a room at the end, more models and lights.

I get two errors when compiling.

It runs a bit, and I get a ton of the error message (in the compile) 'WARNING: Node With Unbound Volume'

If I had to estimate, maybe 200 of these.

Then I get a bunch of 'WARNING: huge winding'

then the compile continues.
And it is successful.

The first time the compile ran, I only got the first message, and it was not successful. Second time, both, and sucess. What does this mean?
