Guild authorities are not updating after changing the status of a guild member. For example, I appoint a guild member to Mission specialist, and he does not get Accept/Complete Missions permission with his new position, it must be set manually. Also, when a guild member is upgraded from Apprentice to Normal member, he won't get Use guild storage permission automatically.

Please fix this, the new system makes managing guild members a lot harder.

Same problem here.  I was recently appointed "Mission Specialist", but was unable to accept guild missions.  When I viewed my guild authorities, the "Accept/Complete Missions" box was unchecked.  I had to ask my guild manager to manually check the box for me.

Unfortunately, after the last patch, the box became unchecked again.  So even if you go through the trouble of manually changing guild authorities, the settings reset after maintenance. 

Please fix this, I hate to bother my guild manager every week.  Thanks. 

I'm having this problem as I type - I didn't have issues long ago when we started a guild and were active. Now after coming back and growing, the authorities don't get aded with promotions to other ranks. Quite anoying - was there no fix or workaround for it?

No sadly you have to set them yourself
