I was designing a small 1959 car. At one point, I found that upon forwarding the year to 1960, drivability was suddenly almost halved, with little-to-no change from any other stats.
According to the detail stats section, the problem is a roughly 30% performance debuff from “Top Speed” that suddenly appears when changing the year- however, the actual top speed of the car had only changed by 0.1mph (From 58.0 to 58.1), and lowering the speed to its original value did not affect anything.
Has anyone else experienced this bug? Is it just a bug, or is there something else I might have selected that could cause this behavior?
