None that I'm aware of. Started popping up a few years ago, seems to have no purpose except to inconvenience boxers. Of course I want to accept the invite, I sent it! If it only asked for confirmation when there are items in the /advloot window, it would make more sense. I haven't boxed for a while, maybe someone has a better answer.
My /advloot window is empty on all characters because it was 12+ hours since logging in and I always empty the list before I gate home. This is really dumb. I send Ctrl+I to my other characters to accept the group invite, and this window pops up and even though I tell it that I UNDERSTAND and I want to accept ANYWAY, it declines!!!
