As you may see, the images are a bit.. odd.. to say the least.
Especially the Fae Flayer one, I don't wanna know what is happening in that one.

Update, 1 more weird one, Ice Scream changed, but Fae Flayer, and Boots of the Hero were fixed.

Are these the ones on Steam itself? (looks like it to me)

Whatever is causing this, its not Terraria-side. I have no idea what might actually be causing it, but the assets uploaded for the Achievement data are correct on my end, and there is literally only one asset repository for them.

This might be an unusual user-side Steam installation issue of some sort.
