My derp is just a stupid derp...
I butt rushed the twilight forest, as I had diamonds, but next to no iron. I set a way point at the portal (as I spawned on top of that forest biome that gives blindness) and set a waypoint in the first ore hill I found.
I get killed while in that mine, and forgetting that Blood Magic spawns you with less health (dunno if that fix has been released or not) I TP straight back the the waypoint (I dont like walking 200 blocks with blindness
) and get killed by the exact same mob that killed me before
