Change from 30 to 80 to fix various glitches that occur when carrying a sprite through a pipe, such as the silver P-switch behaving like a blue one, throw blocks never expiring, and stunned enemies never waking up.
Essentially, this skips over a chunk of code that transfers the carried sprite to slot 0 and clears all of its tables, except for $15F6 (the YXPPCCCT data).
