Scenario:

Since the new patch, I've had several blind invites from other players. Upon right-clicking my name, it appears that the default invitation preference has reverted to "Allow Group Invites from Anyone". I, and I'm sure every other player with a high level character, would prefer that the default setting be changed back to "Allow Group Invites from Friends Only"

Hmmmmm. I'm looking into this... with the most recent heave, we changed the way both your difficulty setting and your invitation preference are saved. They used to be stored on your local machine, so they applied to every character on any user that logged in from that machine, and were not available if you logged in with your character from another machine. Now they're saved on our servers, and the settings are specific to each character.

Looks like it's not working quite entirely as intended.

Thanks for the reply Anson.

So THAT'S why I've been getting low level characters lately "wanting to be my friend" and begging to be power leveled....

Thanks for the heads up....<me walks over to set my character as BUSY>

I got that same thing last time I played. Lotsa people inviting me and I join them only to find they are level 6 and asking for PL.
