106nm at 90kts is a very short flight so I find it really weird that you seem to think it is long. 551nm in a C208 is much closer to 3.5 hours so it seems your trying to pad your rant.
As for “random mission generator”. Yep, that’s what I think of all the third-party ones too. So, I’m not surprised at that.
As for other bugs, especially ATC. Yeah, it’s ■■■■■■. But unfortunately par for the course. I had high hopes for it in 2024. Hopefully they will be back from leave soon and get some good fixes in for ATC and missions. But I’m not that hopeful.
Fortunately for me, I find all mission generators boring so it doesn’t bother me. I just plan my own flights.
