Looks to be much too late for player insight, need to have all that data ready to go in your initial post for a player. Other players likely saw it on the 14th, but saw that they would not be able to help, and moved on. Your current finance page shows no cost to give the loan, no interest paid, and no record of loan payback.
The only other thing that I am curious about with what you said, is how did you know that you gave a loan to that particular country? Especially, if your concern is that this information was not present in the "loans you've given" section. You don't get to pick who receives your loans.
Again, unfortunately, it much too late for us to add facts to this investigation, but the above is a bit of a mystery to me. Even the GM is unlikely to do anything at this point. Always add your country and world. If you had done that, you likely would have had an answer almost two weeks ago. Might have been from me.
Brianf,
You provided the data 11 days after the first message.
It is hard to see what happened.
You provided a loan, means you offered one.
Loans you offer are not always taken. sometimes the offer stands and there are no takers or it happens much later than you would expect.
I can say that the loans function is running unchanged for many years now and we have no record of any lost loan.
There were millions of loans.
Next time, indeed, please provide the data the first time you post.
