Tradelist isnt exacly proof of anything, anyway you dont have any pictures with you even holding it?
As for the donated items, if they are the same as when you bought them from Larva then you got nothing to worry about, they will be refunded when Larva confirms it.
P.S. Phoenix Claw disappears when you die with it equiped, its not a bug, its serves as a scape doll then disappears.
Good luck.
( I guess a rollback then? you will have to post your gc and slot number).
