My issue with it is that it keeps happening and it doesn't have to. Like being the third time they've forgotten to ship dreadlocks. Or how this time they outright forgot to put the correct head on Scar. Like I'd understand it for Celtic and Chopper given we never see their faces, but Scar's is in the files and on the promo art. We've seen his face in the movie!
Though I think my favorite error is the plasmacaster ready animation. It's just the default/Jungle Hunter. And that might be fine to some degree but it's been in the files since City Hunter.
