Well, I think the 35+ crash issue might be caused by bots (I've only tested with bots), I was messing around with some bot code because I didn't have enough people, and I got lucky.
36 players, me and 35 bots, without server crashing.
The issue with this, is that it seems to only work at random, so now I need to test this with 35+ real players so I can see if it works.
