Now before I go into this, please let me excuse if this comes off incoherent. I'm not too great on testing software.
I have noticed that there seems to be a bug in the way tourism is calculated. I had a game where I was breaking even, income wise. I then saved that game, and exited the game. Upon loading it again, my tourism income was cut in half - I was now losing money. I then saved the game again, exited the game, and on reload tourism income had dropped even further.
2 things to note: The game was started on 1.0X.008 - and the reloads were on 1.0X.010. Also, the xenophobia event is currently running. Could it be related to that?
