Down-training pilots and CI effect

I recently down-trained some of my large pilots to medium pilots. I see my CI getting a mystery hit (70->65) because of this (no delays, cancellations, unhappy staff etc. & just raised my marketing budget). That is weird. I guess there should be option to pay them the same salary as a large pilots without getting CI hit.

Downtraining shouldn't impact your CI....

Are your delays under 10% and cancellations under 2%?

Did you fire any staff at the same time as you did the downgrade?

That's what I thought so I chose NOT fire and just re-train.

punctuality 96%
cancellations 0.4-0.7%
personnel morale 100 / staff levels at least 100% as I like to keep it in automatic
weekly revenue 42 M€ / weekly marketing is now 2.4M€ (2.1M€ in past and CI was then stuck at 70)

CI still going down. Bug?

Were there any world events that coincided? Those can sometimes affect CI. One day of bad thunderstorms causing one day of delays (that don't otherwise significantly affect your delay percentages) can drag down your CI a lot. Too much, IMO.

Thanks to a comment I became aware that I actually down-trained my pilots as well, and had a hit in CI, and CI continued to decline for the months to come, even with increased marketing. Only after many months it started to rise again.
