The game has a hard time loading before some updates the game ran very well. When in a sever game like bedwars or skywars or eney where you needed to act fast it did not let you, chuncks took a long time loading, and when you tryed opening chests, inventory, menu, chat, and emotes the loding came up, this made it so you can't open anything, brake blocks, swich hotbar items, open inventory, leave, and atack. This led it so you had to close out the game. And when the chunks did not load you could see other players basically everywhere so hide and seek games will loose there meaning. This may make its so players also have a type of cheating.
Update: blocks become gost blocks when is loaded in a way where can be used for x-ray cheats, also when you dont load you game menu like one time in the lobby it loads fine but then when you in a game the game does not load it just has that loading screen where you cant mine, craft, and acully everything really except walking and runing. Also this happens on every game where there more players around you, also on evey server. Its kinda a crash the game just does not work and even if you are waiting the loading just wont go away in pvp this is a bad thing you cant fight, and chunks and blocks dont load.
