Can anyone help me with this error:

deferred inserts:Item 0x433a3158 is supposed to be on Character 0xd1875, but that character cannot be found.
Server Shutdown: reading data
Execution aborted due to: Data file integrity error

It´s not letting pol initialize anymore.

Thanks!

Your data files are corrupted, properly because you are using datafiles from different saves.

Best way it go back to a save you have all the data files from, but if that is not an option you will have to open your data files and remove item 0x433a3158.
But you should know that you will properly have to remove many items, depending on your state of your files.
