While in creative mode I attempted to use the loom with the new banner stencil "Snout" with a red banner and white dye and it caused the game to crash. (Not sure if it matters, but I thought I would let someone know.) I uninstalled beta after I was unable to use a treasure map found in a sunken boat in beta- creative. The markers were all stuck in the lower left corner of the map even though I traveled 2000+ blocks in the direction of the "X". It didn't cause a game crash though, just the attempt to use the loom with the new stencil.
