Thanks for the reply @Zachary Whyte
Unfortunately, the furthest back savegame I have is on 12 December 2033, but the loan was taken on 1 December 2033. I've uploaded that save game "Joshua Chan Banbury (v03).fm"
Though I am pretty sure the transfer budget or the bank balance didn't increase because of the loan. Are there any other place that the loan amount could have gone to?
