Okay, should be fixed. For some odd reason, Illustrator chose to save the gradient as a .PNG file for *some* of the cards. Not all, just some. The ones it did, I loaded up in Illustrator and it showed them fine at the time so I just shrugged my shoulders.
Since I finished up the cards just before I had to start cooking supper I also did the unforgivable - I zipped and uploaded WITHOUT actually testing them in Tilt.

Rest assured, they have now been tested and appear to be working without issue.
Take a look and let me know what you think. If you see anything odd looking let me know. There's something I see that I'm not sure if I'm imagining it or not and I want to see if anyone else sees it because it shouldn't be there.
Corrected file is in the first post.
And thanks again for the donation!
TP - version with pips should be a day or so. Should hopefully be pumping out lores for both decks at that time as well.
