Solution
If you were using Immersive Water mod:
Unsubscribe Immersive Water mod
Exit to desktop, then relaunch the game
If you were using Climate Control mod:
Unsubscribe Climate Control mod
Exit to desktop, then relaunch the game
If you were using More Vehicles mod:
The save will not work without More Vehicles mod as it has already changed to the new vehicle limit
You'll have to unsubscribe IPT2 and any other mods that can't handle larger vehicle limit
I'm not currently aware of any way to revert back to the vanilla vehicle limit (although you could try LSM Safe Mode described below)
If problems persist, try using LSM Safe Mode options :
Subscribe and enable Loading Screen Mod (LSM)
In LSM mod options, enable the "Safe Mode" options then load your save game
This tries to avoid and ignore errors, and will also try clearing lists of vehicles and cims, fix broken roads, etc.
If it works, save the game under a new file name, then exit to desktop - next time you load it up it should work fine
