Your username: simpl1city In which minigame/server does the bug occur: Parkour, on the biome quest map. Detailed description of bug: I get kicked upon joining unless I move as soon as i'm teleported. Only happens on the Biome Quest map. I'm using 1.12.2 with LabyMod and Optifine. See attached.
Just want to add here that I have been getting this issue as well and I'm on 1.8.9. This bug has only started occurring recently.
