Full load savestate during Bowser fight glitch

[cbrgray]

Saving a state and then performing a full load during the Bowser fight causes a tile data glitch.
Workaround - just use normal load and it works?
Also occurs in Hookbill.
Probably the same as #23 - caused by new tile data being loaded into VRAM to display the boss partway through the room, but the savestate loads the initial tile data from the start of the room.
