I've made a few attempts to get in to playing again recently.
I'm increasingly convinced that there's some sort of RNG that determines what kind of gameplay you get every time you start a play session. Like, you can be having a pretty good match, save, come back a few hours later or the next day, and you are playing an entirely different match. If you're batting, the bowling lines will be completely different, frequency of wides/no-balls completely different etc.
If you're bowling, it will be the batsman's mentality/approach, chance/wicket frequency etc.
It's really odd. I can't think why they would do this, but I'm becoming certain that it's true. At the very least, the match settings/difficulty are randomly changing each time you load.
