Our DBAs are actively working to resolve this issue. The initial cause seems to have been resolved but as this is still affecting some players it is still being investigated.
Please continue to report this problem via In-game GM reports. I'd suggest putting in a petition each day that the bank limit has not been reset for your guild. Be sure to submit your reports with the character's being affected so that our DBAs can correlate the data.

1st - Is it just me or has the Armory not updated for like 2 weeks?
1st - The Armory updates on a very regular basis. Sometimes there can be delays or problems but we are continually working on improving it to stop this from occurring.

2nd - Question how exactly are "inactive teams determined"?
2nd - We don't have any exact details to provide regarding this, just keep playing your games and it won't be a problem.

My Combat log filter is set to the default "Self" filter, but crafting results still show up in it from other people.
We are aware of this issue and are working to resolve it.
