The game wasn't designed to deal with "stackable" extremely high value zero tt items.
There're so many easy fixes.
1) Make them non stackable. Pain in the arse I know, but worse case is you lose one deed not all.
2) Allow a limit sale marker you input on each deed. Say its set at 1000 default for a CLD, but you can adjust it.
3) Ban orders for all deeds, and have a 5 minute time before a listed sale goes live.
Different issue, but adding a non TT tick box on items like amps, has been talked about many times.
MA has known about these issues for a long time. Other than the Gold card, they appear to not want to help further protect avatars assets.
I know a few players that have left the game over deed trade screw ups. We are not talking a few ped, but thousands of dollars.
I don't know how many times it needs to happen, before MA proves to the community they're listening.
This should be about fairness, justice, and old fashioned community sprit (nothing less)....It can happen to you. I stand by Helena 1000000000000%.
