We have been recruiting new guild members recently up to the point when we reached 50 players in our guild roster and further invites become impossible.
So, we figured out that guild membership can be extended by purchasing capacity upgrades from the Guild Registrar NPC (we headed to the lady Beaulieu in LA).
And now our guild is facing a problem - after choosing 'I want to apply for a large guild license.' the NPC say's: "... One moment, while I check your records." and "Hmm, your membership is not large enough. You need more guild members before I can give you a bigger license."
From what I read in gw2wiki: "Initially, each guild is limited to 50 members. You can purchase the following capacity upgrades by speaking to a Guild Registrar in any of the major cities or WvW, only if the guild membership is at least 80% [verification requested] of the current maximum size." At guild talk under topic 'Roster size info incorrect' guys are discussing the issue where they reach a conclusion that the limit might be up to 80%, however it is still unclear if maybe there is a check on guild member activity (column 'Last Online' in guild Roster).
Our guild has 50 members in Roster, 33 of them were seen online less than a week ago. And we are still unable to purchase the upgrade.
What prerequisites do we have to fulfill to be able to extend the guild member capacity?
