Seems like I can never do anything right the first time!
1.15.1 had two minor issues that I thought I'd patch up before I start working on 1.15.2...
-Fixed, New games in 1900 Easy mode started off with $400 Billion. That was a little bit too easy (and a debugger amount so I can test things without playing the game.)
-Auto production was producing too many vehicles in a factory. I believe I have fixed this. It will require some more testing however.
