Implemented Inventory and questbook wiped after being offline for 15-16 days

Me and a friend of mine (alexhojris) logged in today after 15-16 days offline and found our inventories wiped and the questbook reset. The island was still the same and my title is still the same. We haven't changed minecraft name and don't know what might have caused this.

 

Oh... So all of our upgraded ichorcloth gear is gone.
Well. Thanks for answering so quickly.
Will you be hosting AG2 when it's out?

 

There has been talk of an AG2 server. I think they are waiting for the pack to have quests before they make a server for it
