WowAce

I use Bartender 4 on my two 80s, one of which is a feral/feral druid. In cat or bear form, when I attempt to use a forms-only ability, it kicks me out of cat/bear and into the night elf form, triggering the ability on the corresponding NE form ability. for example, in cat and bear forms, the #3 button is Mangle, and in NE form #3 is Starfire; in either cat or bear, attempting to use Mangle will return me to NE form and start casting Starfire. This happens in both my tanking and DPS spec, in both cat and bear form. If I disable Bartender and use the default WoW action bars, this does not happen, but I can't play like that anymore. this only started happening today, 10/28, with the newest Bartender update.

OK, further playing has shown that if I mouse click on the buttons, they work properly, so it's a hotkey issue- the hotkeys are staying mapped to my NE form abilities, not the abilities currently on Bar #1 (which is actually bar 7 or 9, depending on forms). What's the fix?

use /kb and rebind your keys to Bar1, maybe they got jumbled up somehow.

I have this problem as well. Reverting to an older version of bartender works fine. It seems the number keys are not getting assigned to the active bar, but always bar 1

EDIT: I reverted to 4.4.10 version, don't know about the intermediate ones.
