So i just updated to a newer alpha build (6915) from a pretty old alpha build (6583).
I noticed i had an issue with the right click pie menu being different in a way that makes it impossible to buy back objects that have been deeded to group. I can set the object for sale (say to 0L) but when right clicking the object to purchase it, there's no "Buy" option.
There is a "Pay" and "Take" option that are both greyed out but there's also "Wear" and "Attach" options when clicking "More" which i can choose but those options fail since it's owned by another owner (The group).
I can return the object, but then it goes back to the last owner's lost and found which is undesired.
To reproduce, make a new object or use an existing one and set the permissions to NO COPY, NO MODIFY, and TRANSFERABLE.
Then DEED it to a group where you are an officer or owner so you can modify DEEDed objects.
Then set the object for sale (L$0 to avoid paying in to the group) and attempt to right click and buy it back from the group.
