I'm rotating this combo four times with the "r" key. The original frame is facing south, (With rotation at "0"😉 with the Cyan Cset portion filled in the lower half. (Ignore the upper gradient. That's IRFanview's work, not mine. 😛 )

Still in Beta 12c. Here are a few more details:
Try this for yourself. I have something completely set to the Cset2 usage of "6" and I flip it vertically on the combo page and the "6" turns to a "2".
It turned a "3" into a "1"
Then it turned a "1" into a "0"
When it's at "0" it doesn't transmute into any other number.
Hell, it gets weirder. Try clicking on at least two minitiles of unwalkability for it. It actually affects the Cset as you flip.
I'm also rotating this combo, and it's doing nothing, then flipping it vertically, then doing nothing, then flipping it vertically again.
* Pressing V in the combo editor dialog will no longer corrupt the preview tile and the CSet 2 field. ( DarkDragon, 2007-08-22 01:14:33 )
Confirmed that and this bug are fixed in 536.
