Thank you for your honesty but for me personally this means that I probably won't start another save in this game.
I play the game for longtime saves and the most fun part for me is developing youngsters, which I can't really enjoy knowing that the development system is broken. Maybe that's unfair because apparently in the past the system was worse, but I started with FM19 and it didn't really bother me until FM23, but now I just can't unsee it.
It's a bit worrying though that apparently you can't really do anything about it and it doesn't sound like you are planning any kind of "development revamp" for the next edition, but it's fine, I know most players are not that bothered by it.
Actually it feels better, now I can make a clean cut with this game and don't have to have hope in small "updates" that in the end don't change anything at all.
Don´t get me wrong, you made a good game and many people have fun with it and that's great, but it's just not for me anymore.
I will have an eye on future editions though, maybe this aspect will get better and you will get a fan back!
