Can you increase time before players are promoted a bit on spawn? I'm using MySQL for usergroups and it has over 100 players so it takes time to load. Users from donator group sometimes get promoted to their old rank then i have to manually add them back again.
Someone with more knowledge most on this subject will most likely will correct me. Anyways.
According to what I just read on your post, it doesn't really make much sense. If you're using SQL, then time isn't really such a problem, if you
are actually using MySQL, time really still isn't a problem. That's the magic on how an SQL server works, time isn't really a problem in a factor.
As for speeding it up, it's just a timer every 10 seconds. What your real problem would be is well, actually I have really no clue, maybe utime being delayed or something. Because I'm not sure how or why your donator group is getting affected. It sounds like something else to me, because your donate group should be at -1, which means it gets ignored..
So really, I have no clue how to fix your issue.
