I was trying to find a fortress with nether wart for my survival world (I didn't find one if your curious) While doing so I went over the bedrock and realized /locate fortress wasn't working (MCPE-24713) and went below the bedrock to see everything except bedrock and netherrack's textures were corrupted so I opened the creative menu to see half of the game's textures were corrupted and looked bizarre and before I went above the bedrock they were normal I do have a few resource packs fire in the furnace (an addon that adds animation to a lot of blocks) in particular may have been the culprit but I used it before and it never corrupted until then! Oh yea and the game crashed before I went above the bedrock that may have also been the culprit
