If you shoot an arrow into a block close to you it will disapear into that block and then pop out when you move closer to it. Btw, i did this in f3 mode and had the thing with outlined enteties enabled. I dont have the time to test without it right now. PS: the arrow entetie had in f3+B mode a eyeline, is that correct?
