NOTE: Servers migrating from v3 should add the fixCollision section to their CoordinateOffset config.yml. However, this fix is enabled by default even if these lines are omitted.

Several fixes to 1.20.6 bugs present in PacketEvents v2.3.0
Fix players being kicked while near a horse or wolf that is wearing armor (packetevents#827)
