Hey. I just did challenge mode with my character and left the group. I planned to join the next one, but the
addon tells me to disband my premade group first. I click the button and boom. The following message shows up:
(This problem is only with one character. Others work like charm. I've tried reinstalling the addon few times and
to run oq without any other addons running at the same time. I also deleted my wtf folder just to be sure that
it doesn't contain anything that prevents the addon to run normally).
