Glitch with Scholar and A5/A5S introduced by patch.

[FoxyAreku]

No macro needed, really. Shift+1 switches your first hotbar to hotbar#1, Shift+2 to #2 and so on. Unless you changed that keybind, of course. So it's pretty easy to fix, but I agree that it's a bug that shouldn't be there.
Haven't tried A5 since the patch, so I don't know if I'd get the error as well, but I rather assume I would since I'm on PC.

Most PC players use shift as a modifier for abilities so that's not a fix.

The pet hotbar also isn't on the list of hotbars that you can normally switch to I think, so I don't know if that would work anyway.

Really weird that this is apparently only happening to certain people? If this was happening to everyone I'd think the forums would be exploding, this is really unacceptable.

Which is why I said "unless you changed that keybind" =) It's the default keybind to change the first hotbar. Even if someone's removed those keybinds because they use shift+# for spells, the keybind option is there so they can set it to a combination that suits them better.
I don't think you can manually change to the pet hotbar like that, no (not logged in, so I can't check for sure whether there's a keybind option for it), but usually people in this thread seem to want to change away from the pet hotbar, not to it =)
And of course, I'm by no means saying that it's an "acceptable" bug. Just pointing out a way to hopefully deal with it until such time as they hotfix it (which shouldn't take too long, I hope).

Anyone done A5 today as a scholar or summoner? Did they fix this?
