/*
The thing i've discovered is when using an item in air, it needs to send 2 packets.
I believe the issue is that this needs to be flipped with the packet above while still
sending block info.
Otherwise no idea, the disadvantage: Interact does not get fired if you right click
special items. (there's quite a few...)
