World capacity

I had a relatively simple sublevel that surprisingly was at 107% of the vertex limit according to the World Capacity option in the desktop editor.

So I made a copy of the sublevel and deleted everything in the hierarchy. I was still at 68% of the vertex limit.

I then started reducing the player limit. When I got to 8 players, I was then at 20% of the vertex limit.

I suppose that it might make sense that the vertex limit would depend on the player limit but surely empty worlds should have low or zero vertices? I wonder if there is a bug in the world capacity vertex calculation in the desktop editor?

[EDIT] I just tried the same thing with a new world - no content. Same thing. If I set the player limit to 8, the world capacity indicator said that I was already at 20% of the vertex limit. If I set the player limit to 32, I was already at 68% of the vertex limit. Seems like a bug?

If it is a bug I can report it.
