It's been noted that in other threads, taking the Popular racial trait at -1 or -2 will lead to negative tourism in 3.5+ and they are working to limit that to just 0 income.
Check your racial traits. It's not like being unpopular could have ever have negative side effects...
Oh no haha. I got the polite fk off. haha Sorry. I promise I did look and google it. I would not have made a thread otherwise.
The surprise was I expected to not make much profit through tourism (because it felt rather broken) rather than have it swing into a cost, regardless of how high the modifiers were. The patch looks to have fixed the issue by making it less extreme and now it's easy to compensate. I am glad they fixed it.
