@MojangSupport I assume you're aware of the bug with clipping through the ground when in underwater, especially with bubble columns? I often work myself away from the magma block but drown or almost drown because half of my body is stuck in stone.
I'm sorry that's happening to you. I would go ahead and report that here: https://bugs.mojang.com/secure/Dashboard.jspa … so that the developers can see and look into it further. ^AS
