HSX has a rule about no attachment/adjust for uncredited roles. Period. ...well unless your name is on the poster, in big letters in the trailer you promise to come back for the sequel and just is omitted from the movie ... smile DMac..
Examples: ALAPA in ANAL2; BWILL in OCEN2; ...and AFINN in the same movie who's role in the plot is something of a spoiler.
MGIBS in FATHR (before my time at HSX, but before current StarBond system); CHEST in PLNTA (You damned dirty apes); PBHAL in RUSH3
On the other hand, AHOPK was uncredited in MISS2 but is attached on HSX, but the movie was before the new system.
