TE_Morpheus

Hello, I am playing B-Team now for about one week and now i have a problem. I went through the nether portal and was killed by a ghast as i respawned i spawned in the ground and fall off the world. Then i respawned again and i was stuck in the ceiling of my house and was killed again. And Now my hitbox is too big. I restarted the game already and nothing changed. Please help me, thanks Toby
