Cannot reset instances 5.0.4

[Sauna]

Hello there,

I've been boosting 2 RAF accounts with my main account for the past 4 weeks with no problems, but after this latest patch I haven't been able to reset instances.
I can select reset all instances with group leader and the "yes" "no" option will pop up, but the "yes" button does nothing. The "no" button works as intended.
(Reset won't work no matter which account is the leader. Main account / RAF1 / RAF2).

If i want instance reset, i have to invite my girlfriend to party and make her the leader. She can reset my instances no problem.

Anyone else experiencing somewhat similar problem?

Cheers.

Are you certain it isn't any addons interfering? Have you updated them to the "Pandaria" version?

It really look like an interface issue.

Once i got home from work i did a little testing and it was indeed an addon causing this issue.
To be more accurate, an addon which calculates instance visits / resets times.

Cheers to both of you for help.
