Sometimes when shifting into cat form, the following line will fail to evaluate to true:

if(not RequirePower or RequirePower == UnitPowerType('player')) then

The UnitPowerType('player') call will return values reflecting the human form, so "0 MANA"

Technically this is a bug on Blizzards end, but perhaps it can be worked around by adding a small delay to the Visibility update.

You should update your clone, the whole logic with power for feral didn't make the PR/merge,

Closing this one, as it is an issue on our end only.

Oh right, I forgot about that. I would actually like to keep the mechanism of only showing combo points as feral while in cat.

I guess I will have to see if I can find a way to fix it while keeping this mechanism in place.
