If a player goes on hiatus he should not have any items in a player owned structure because he cannot properly take advantage of asset safety in case it kicks in. What happens is that if the structure ceases to exist for whatever reason, the items will go into asset safety but as far as i know the player on hiatus will not recieve a notification (it could be an email) that this is the case, but the way asset safety works is that you have to act within 20 days or the system will automatically move your items for you and slap a fee on it. This means players returning to the game may find their stuff not only moved to a different system but having to pay 15% fee to get access to them again. Is this really what CCP intends?
