Well, I suppose that my memory is merging RCT and RCT2 in my head. After all it has been almost 2 decades.
When I was referring to an old save, I meant an old openRCT save. They were 10% for me, but that was a while back.
Sorry for the confusion.
I've really been enjoying this product. I've noticed recently though that all scenarios are starting with 1% interest rate. Is this a feature or a bug? I'd like for the scenarios to have the default interest rate.
