Warped on Crimson slabs Crash the game.

With a crimson slab placed on the lower half of a block position (On the ground) and the position above it having warped slabs (Floating above it), attempting to place a warped slab on the crimson slab (between the floating warped slabs and placed crimson slab) the game freezes, and proceeds to crash. This also works when the crimson takes the place of the warped slabs.
