I just completed a cardmod but I still have a little problem that you might have encountered before;
So the mod works for all window sizes except when you make them the smallest size (so it uses the *_nf_lowres folders from \NewTable\Common\Cards).
Then it looks like this when you resize.
It appears to overlay some version of a Joker card I once made (letters L OL) on it. I completely removed the software client from my computer, manually removed the FTP directory from the Program Files directory, then downloaded and installed the client and applied the modfiles again.
I have checked and re-checked every one of the SVG files with SVG viewer and Illustrator and I can't seem to find where it's getting that Joker graphic from. Layout.xml doesn't reference it so I don't know where to go next.
I've saved them in Tiny 1.2 SVG format in Adobe Illustrator CS4, maybe it might be messing around with the internal layering of the files (since I was working with one masterfile from which I saved all the individual cards)? If anybody knows how to fix it let me know, I'll put the updated version online for everybody to download.
