Don't play the game unless you're in a vip (i think it'll save ur stand from being deleted).
So I guess stands are being deleted by a hacker. The only way I think it happens is being in a game with them. Try not to play a lot and get your stand deleted.
I know the game is still down, but if it comes back up (unlikely for a while until they remove abd assets) just be safe with ur stands ok ty yes because people have good stands yes
