Not-a-new player asking a new player question. Some nublet may find the answer helpful.
I’ve had this expired contract sitting in my Outstanding Contracts tab for around 13 years. I can’t - for the life of me - figure out how to delete it.
Laugh at how dumb I am if you must, but tell me how to get rid of the thing please.
Mr Epeen 
No jokes from me here. I would file a ticket to remove it. With it that outdated, I suspect the items are no longer available to be retrieved on the database.
Have fun!
Im fairly certain its the rare „open a ticket to have a GM fix it“ situation.
Edit: I remember it from this thread: Contracts Bugs
This is Tatiana’s revenge for you not accepting her gift, it will stay there f o r e v e r.
