looks like they paid some attn to group issues this time. the one that seemed to be more relevant to the large group issues was:
- Inviting other player characters into a large group who are in a different zone will no longer cause de-syncing issues or disconnects from the game.
also, something i had seen in ralcores poi events:
- Fixed multiple instances where all grouped player characters could not use doors.
and this one kinda made me wonder what would happen in ava when the group leader died:
- Fixed an issue where an event would deactivate for an entire group when the player character that triggered the event died.
but... my favorite (unrelated to groups) was:
- Skeevers are no longer invisible while in their idle animation.
stealth skeevers... scary... ;-)
