Dude! Where's Your Stuff?

Personally I would have preferred a different asset safety for abandoned citadels.

One that puts your stuff into asset safety, but it can only be accessed after 30 days. 

That way it's not gone forever, but it's effectively gone for the short term. 

So if you're away from the game for ages, and eventually come back to Eve Online, even if your stuff has gone into asset safety from an abandoned citadel being destroyed, it'll most likely be waiting for you when you eventually login again as the 30 days has probably passed.

Unless of course CCP needs the database room, in that case it's GONE!
