Anyway to make it become active at a set time after a player goes offline? so for example if there is scrap in the tc and the player is online it won't take the scrap,but when the player goes offline it will start protecting and taking scrap at a set time after they disconnected say 15 mins (so you cant disconnect during a raid or just before)

If you could and servers could get the right balance it would be game breaking, combat offline raiding and slow clan progression as they would need scrap for base protection and not just pump it all in work benches

richhp123 -- take a look at Anti-Offline Raid, it does exactly that but without the scrap cost.
