Datapack works on single player, but not multiplayer

Not sure why this is, but it works 100% on single player and every now and then, 1 person can use abilities on multiplayer.
I will provide the tick function and playerloop function, and can do more if needed. Please look through this and see if I made any mistakes, or if there are none and you want more code. Thank you.
