Hello I've had this crop up a few times and want to know if the dev team considers it worth reporting. For example I have a save from 42C that won't load in 42D (and actually crashes the game). Is that kind of behaviour just to be expected, or should games be loadable between versions? And could I suggest locking out old version saves when they become incompatible?
Nope! Don't even bother. I plan on doing save lockouts at some point, I've just never had the right spare moment.
