Any number would work.. I just said four because real bf2 has 4 teams. China, USA, MEC, EU.

As for the rank reset.. Have you changed anything on the server recently? Something has gone weird with csstats.

I joined your server. Rank was reset, said I had zero kills. Checked /rank, said I had 20 kills.
Played for a while, got 16 kills, got promoted etc etc. Checked /rank, said I still had 20 kills.

Looks kinda like your running csstats twice or something?
The number of kills in the bf2 text thingy is straight from the csstats database. When you spawn, it sends a request to csstats to get your number of kills and formats the text to have that number.
/rank does the exact same thing. The fact that /rank is bringing up the old numbers but not updating.. weird.. Look into stuff like amx_plugins and see if you can figure something out.
