BF0D: Clear bit 5 of every object's flags
Used by the routine at OBJECT_DONE.
Bit 5 of +7 asks RENDER_DYNAMIC_OBJECTS to copy the object's part of the buffer to the screen. The main loop (OBJECT_DONE) calls this after drawing a new room and copying the whole buffer to the screen at once, so that no object's part is copied again.
