// Fix a bug in Paper 1.8.8 when using ViaVersion on a 1.12.2 client.
// BUG: Player can infinitely increase their level by placing a block at their feet.
// It doesn't take the block away but still increments the level.
// This doesn't happen in Spigot, but does happen in PaperSpigot due to a BlockPlaceEvent being incorrectly fired.
// The solution is to wait a tick to make sure that the block was actually placed.
// This shouldn't cause any issues besides the task number being increased insanely fast.
