Tested with b6, it actually slows down this crash error by a lot, but it can still happen if you spam games like csg.ario

sv_cheats 1;developer 1;dumpgamestringtable to show stringtable
when reaching 65 536 (aka 2^16 = 16 bits), it will cause an overflow and crash your game

You should be safe if you don't spend too much time on this map. If your timelimit is greater than 20 mins, or you spam games on it, here's a solution that will work for every future map, and will fix this issue (or delay by at least a day - and btw you shouldn't let your server running for an ENTIRE day on a single map) :

Here is a fix if you are running a server with Sourcemod (compiled in 1.10)
