Isnt it better to use in the table object_data the PlayerUID to identify the owner instead of the characterID?
Building a Wall with charID 4533 then i die, new charID is 6521 so im not longer the owner of the wall.
Epoch Team should change the actual CharacterID to PlayerUID and then add a new row like ObjectInfo to store informations like the code of a safe or lockboxes.
Its also better for a cleanup of mySQL.
Sorry, english isnt my first language.
