Solution: don't use Spigot forks that mess with random stuff in order to make minuscule optimizations.

(ofc Retrooper/DefineOutside decide on outcomes for this stuff)

Not a PacketEvents issue. Issue tracked in CobbleSword/NachoSpigot#356.

Tomorrow I will look into it, but something questionable is this works on any other server software.

NachoSpigot now works. We recently added a Paper injector, which is more efficient on Paper software and luckily works on Nacho. f9136db
