@RedRoseWarrior Platform? How did it happen? Has it happened again? Have you tried reinstalling if it has continued occurring? 
Might be related to this other issue we are noticing here.
@polyester Is this still happening after you’ve scrolled through all the way, closed the menu/closed Guild, then reopened Guild? Please also try closing/reopening the game. I had it appear a few times but did the former (I needed to cycle through it altogether). If it keeps happening after that what’s your platform?
The dev team actually fixed as many instances of this occurring as possible, but there’s still some rare occasions where it’s happening again.
@Rylo_Ken Sounds like you need a good reinstall
