So I was going about my survival day when i came across a magma cube, floating above the flowing lava.
I was curious so I tried to recreate what I had seen in the previous world. Doing that, I figured out that I could also float about the flowing lava.
This became a problem, because If I were to place a slab on the edge of the flowing lava, then stand on the edge of the slab, it would set me on fire, even with the stairs.
I began to do some more testing with the magma cubes, and found out, they were also bugged on a whole block of lava. They seem to dip down only a tiny bit into the lava, where as previous versions, they would be semi-submerged
This is all I found, hope you find out what's up.
