IMPORTANT NOTES | UPDATE AT YOUR OWN RISK
This is a very important breaking update. I started using PacketEvents as library instead of my own and changed the obfuscator, so this may have caused some bugs even if this version was hardly tested on 1.8 and 1.21 in servers with +100 players without any issues.
Some customers may not be able to run this version; if that's your case, then open a ticket on our discord and we will fix your license as soon as possible.
It's recommended to reset your config entirely or manually apply the changes you can find here.
Plugman reload is not supported anymore.

I put a lot of effort into fixing some new exploits and found a new, unique way to fix them. Thanks to the Xynis guys and the Smog owner for giving me the willpower to take this big step.

Special thanks: Polar staff, retrooper, noopey , MachineBreaker , SquareCode , @meowk1e, BadNull, NoJokeFNA for the help in general!

I will donate to PacketEvents soon, thanks for supporting LPX!
