Game crashing when placing painting in snapshot

So I was playing the most recent snapshot and I decided to see if there was any knew paintings so when I went to place one my game crashed and I just thought I hit a wrong button that closed the game so when I reopened the game the two blocks I placed down to put the painting on was gone and when I tried again the game crashed again. This was in a creative world and not sure if it happens in survival. Hope you guys can fix this bug.
