Prestige and Reputation marketing not working

I’m not sure if this has already been changed in 4.1, but I can verify for certain that Prestige and Reputation marketing are not having an effect on company prestige and reputation. I suspected this for a while but I didn’t post this until I heard for certain that they’re supposed to have an effect even when selling no cars. (343.4 KB)

To demonstrate, I have this campaign save file. I started with unlimited money and maxed out marketing spending, then let it run for 20 years. Prestige and Reputation are still exactly 0.
