New Unit Cards

[Mishmish]

So I've been working on adding a few new units to the game, and for them I've made new unit cards. Long story short, after much mucking about I finally got them to work with one small problem: when highlighted they didn't turn yellow. No problem I thought, I just need to make the bg of the card icon transparent (alpha channel). I did that and now they're wonky as all get out. The icon png that should be showing up isn't, instead it's random other icons. Once there was a ballista icon instead. The weirdest part though is that the masks are working fine. So there's some floating clothing and then some other random nonsense. Any tips? Names are all correct, and I've tried making the bg opaque again, as well as creating new images and just copying over the art.

Still no idea how to edit posts, so I'll just add this here. Prior to changing the background, everything was perfect except for the cards not highlighting when selected.
