Love these changes. These wrecks are how their low-browed terrestrial cousins should have been. And the salvaging is long overdue.
My only suggestion is to extend the "salvagable" timer on aphelia owned tiles from two days to a week before full deletion. Players will clean those up quickly.
For every well meaning DarkHorizon there are twenty market spammers with horrendous advertising and lag inducing sales pitching constructs. I am still against having Aphelia run markets at all (power to the players, players run markets, advertising run by players) but this is still a good step in the interim.
