This dose not bother me to much, but it is still sort of weird, so here we go.
In the building on BSC clan base, before our 2ed merge, we where placing white stained glass blocks over water.
I had to log off while I was in the water, placing glass blocks. When I logged on, I was inside a glass block. I was not loosing hearts or anything that could kill me, but I was in a block. I could easily get out, by jumping, but I kind of panicked at first.
My guess, is that while I was logged off, someone had placed a block where my head was. Then when I logged on I was still in the same place, just I was in some glass.
Thanks
