Double checked how the bags fit in-game. The units are supposed to be holding on to the part of the bag where it goes in near the top. The only unit's hand which you can see is overly big, so it goes through the hand. The more I look at it, the more I hate the texture. I'll consider making a new skin.
Woops, I didn't notice how poorly that fit on. I was too busy admiring the other attachments I made. (some of which I will submit to this site as well) I'll fix that and re-submit it tonight.
