During about an hour and a half of playing this snapshot, I noticed 2 bugs, both of which are major flaws. Both bugs were in the form of corrupted chunk generation, one that created a shadow along a line of chunks, and another that didn't render several chunks. The former bug maintained intractability and terrain generation, the latter bug did not. In the latter bug when attempting to enter the void it would cause the character to float, shake, and moving was very slow. I have several images showing the effect. The former bug did not appear to be infinite.
