Hello all you sexy people!
I reported that on the old boards shortly before it went kaboom and I'm not sure it was taken into account. It might have been reported again since then but I don't know so I'll let you sort through it
That's a pretty weird bug if you ask me:
When you update the guild roster at, say, 8:45, the minutes part of all guild members in the last online field is updated to 45 as well. You can see it on my guild's roster:

Note the last updated time and compare with the minutes value for the "last online" field of all guild members: it's the same (well there can be a one minute difference if you make the update over the minute change, and if members update the roster with their character information it will be modified as well of course).
Thanks,
- Fang
