The most I’ve had is around the 2000 mark. I have heard of this problem before, just I’ve never personally experienced it on the server I used to develop, except once which a relog fixed it as it was database lag from him logging in.
I’ve had Psyco’s version since the day of release and have edited it daily since then till recently, again, it’s more than likely something I’ve edited that’s fixed the issue or there is something you and others are doing that’s causing the problem itself, if you end up using my version and have the issue then we can discuss and I can figure out what you’re doing differently, though that would probably require a database wipe as there is probably some corruption in there now if it’s happened a few times.
