I am trying to unlock the BAe 146 by servicing 75 of them in bonus time. The first one I had counted. 1/75. Every single one afterward has not counted towards the goal. I am sending them off before the marker every single time.
I noticed the same but wrote it off to the fact that I played BRI for the first time in November 2019 and updates probably didn’t change the game parameters in this aspect.
I think it’s only the BAe 146 passenger version that works, which is annoying.
