With the latest update, Android Efficiency (Ultron card #01144.jpg) doesn't render.  Cleared my browser cache and tried on a different browser.  Other Ultron cards render properly.

Same thing happens to me. The file looks fine on disk opening it manually (01144.jpg) but it does not render on game.

Hi @DevoDog and @telemako,

Thank you for your bug report regarding card “01144”. Please note that “01144” is not an illegal card ID; it refers to “01144a” “01144b” and “01144c” which differ in their Boost abilities.

The topic Android Efficiency 01144 should be three different cards clarified this for us.

We have already fixed this issue in version 0.5.9.86. However, we did not update the images for these cards. As a temporary fix, you can create three image files named “01144a” “01144b” and “01144c” in your images folder for these three different IDs. The names of these image files must end with either “.webp” “.jpg” or “.png”, or you can wait for the next image package release.

If you have any further questions, please let us know.

Hmm. Even having files named properly in the asset\pics folder (and clearing browser cache, refreshing and trying two other browsers) doesn't fix the issue.

Sorry.  I wasn't closing the "server" and relaunching.
