this error continued after the patch that was supposed to fix it, I asked in chat as well seems most of the 900s zones also seeing this problem.
I do not receive this problem outside of the 900s zones, my tribe is located in 1020 (not effect by the glitch) but my members also saw the same error while we were in 981 zone.
Hope this helps.
