I think this is worthy of discussion.
Situation:
Player X has a loan with Bank ABC.
Bank ABC closes.
Player X still has an outstanding loan balance but cannot repay the loan automatically or through manual means.
Question of Discussion:
What should happen to the loan when a bank closes?
My Opinion:
There are two viable options in my opinion. But I've added a 3rd for those that don't like the reality of the situation.
1) The Bank owner is forced to write off the loan as a loss, thus closing the account. The account holder is cleared of the loan and any remaining repayments.
2) The Bank owner can sell the loan to another bank or nation. Sale of loan can only be for the remaining loan principal. New loan owner receives all payments and interest.
3) The player can still continue payments until loan is paid off. (Don't like this option, as it gives players the ability close their banks but still collect on loans they made to players.)
Edit - Added 3rd option
