I experienced the same thing running DS over the weekend. When in the Ultraxion and Madness fights my main spell bar was emptied as soon as the ExtraActionButton popped up.
Xrystal, thank you for finding a solution for us, but please can you explain a bit more about your other two patches required to make this work and possibly link to the threads here? I have updated my nUI for the group bug using your patch but am not sure what your overridebar patch is. Sorry.
Thanks for your efforts!
