Just click the upload file button next to post reply (Or what the post button is) And go to the same place and upload the screenshot you have of your items.
This will most likely have to be a Cypriotmerkz refund. There is a possibility some mods and players will help donate to get your items back too though. All I can say is with this, you should be able to get at least some items back. Do you have any proof of the island, and how it is now? And also do a /coop and screenshot that list, and a /trust list. That way we can be sure that you are not just trying to double what you have.
Mods usually don't do refunds of this size. You may get a bit back from mods, but Cypriotmerkz will have to do the refund.
Try to message him in game, or PM him on the forums. You may get a response quicker. (This isn't for sure, so if he doesn't reply don't get mad)
Make a convo with him if you haven't by now. You'll more than likely get a quicker response, no guarantee though.
I dont have much, but i'll see what i have. i might help with the refund a bit. Tell me what you want of these: Also, not the dia.
PC, that is very kind of you. I can possible help too. I have a ton of junk XD I need to sort my stuff, so getting rid of a bit could help. Can't give the buckets back though. Sorry.
