Alright everyone Ill make this short and sweet. As of today (2/25/2014) we had a big server error where it caused the world to become corrupt. I am current uploading a backup of the world from last night (2/24/2014) to which there will be rollback. No I can not refund your items you mined or lost.
However coming very soon will be a new world with a new spawn. When that time comes the old world will remain on the server for one week and a portal setup so you may travel back to it and retrieve items/base stuff/etc. After that one week, the old world will be deleted forever.
I will be placing an annoucnment up when we plan to add the new world/spawn to the server, but I would expect it within the next week or two.
