 '''Additional Notes'''
 "0007d580: 9222007e lbu r2,0x007e(r17)" is loading from Misc. Data, which the AI hasn't updated at this point. As a result, the AI may occasionally fail to compensate for being on a upper level, especially if they were previously
 on a non-upper tile. There might also be similar issues with the Misc. Mount/Rider flag maybe. Anyone looking to modify AI in the future should be on the lookout for calls from Misc. Data and also only make calls to static attributes.
