It appears the consequences of allowing "voting" on the server is this:
It ends up on Siege Destroyer and stays there... forever (once the map is over, it restarts, repeats, etc). Not that there's anything wrong with Destroyer, but again, the huge bias/ignorance against using addon maps on public servers means that this clears out the server and prevents people from getting on.
I wish the Q3 engine had a better delivery system for auto-downloading! (Or at least that OJP Basic had implemented such a thing)
Voting also breaks the vstr cycle, which is a problem, so I'm turning it off. I reduced the number of bots on certain maps so hopefully it won't seem so annoying to people. The goal of having bots is to get people to come to the server, believe it or not!
