512.1412 I think.
(Visit to download old versions for testing.)

Replacing a single-click action with an external image editor hassle.
Yep sadly the whole DM icon editor got really messed up and bugged after last update, not just this part, hopefully we get a fix for it all soon.
I believe I already have a fix for this in place, but I'll run tests to make sure.

I found some things that the 1415 fix missed, and flips and shifts were among them.
Can we get this bug as a tool, the "mirror half the image to the other side" functionality could be useful
