Hey needing some help.
My friend and i were playing on our server today perfectly fine for hours. Suddenly my friend starts lagging badly, chunks not loading, constantly floating above the ground with elytra then disconnecting from the server. when he joins back he gets black screened then spawns in a cave or back where he left but no chunks have loaded and he cant move around properly and falls through map. on my screen he moves perfectly fine. he has tested in other servers and he is fine so its not his internet. please help!
