Bumping this reply. Mayor's clubs NEED to have the ability to show club members' names when they buy from your GTHQ. Members are silently sniping items that others are trading with each other, and its impossible to tell who the culprit is. I've kicked out mass amounts of new members to try to flush out the bad one, but each time I try to recruit more so the club chat becomes a bit more active, someone starts stealing again.
I have purchased a decent amount of simcash over the year and a bit I've been playing (well over what a new Switch game costs; closer to two) but I'm not spending any more real cash until this is fixed.
