Slow Startup When Loading Bans? and Bans Lost after restart

Plugin i just worked on, so basically if you get alot of bans , it will cause the server to freeze when loading , going unresponsive for a long period of time sometimes, and when you restart the server , more than half the bans will be gone this is just a demo of the effect, and how i fixed it using a plugin.
[DOUBLEPOST=1518970269][/DOUBLEPOST]i don't think anybody will notice this unless they do a lot of bans, but just thought i would throw it out there, i believe it is something to do with the game, not oxide.
