Issue / details
The y-cord 256 bugs out and when you use a tool ( right click hoe, shovel, axe )  you fall thorough a block but get rubber banded up but dose effect the hit box so it makes it super hard to hit  the clips are on a realm with addons but it works on singleplayer no addons also note ONLY 256
