The Dink Network

Okay, I am having multiple problems with my boss script and I have no idea what's going on. I have examined a couple other scripts, including ones I wrote earlier for this game as well as for DatB, and I took pieces of the scripts to fix a couple things already, but I can't seem to get the rest of it to work right. I condensed two scripts into this one, and it solved a few issues, but added at least one of these current ones.

Issues:
sp_target(&current_sprite, 1); doesn't work, boss won't target Dink.
boss's die procedure text appears in top left corner of the screen for some reason.
hit sounds are playing randomly

The whole script (minus spoilers):
