So like, if I were to download this scenery 6 months from now, lets say, after there's already been a major update for it, will I have this fix already in it?
We included as they are relased, basically. Even if you download the installer today, it already includes all the fixes released so far.
That's another side effect of having the product in Trial mode...since the full installer acts as a trial, it's in our best interest to have the trial to be as bug-free as possible as soon as possibile, so you don't have to wait for patches.
We are working on an entirely new installer, which will automatically auto-update all our products when launched, so one will not have to download the full installer twice, and not have to scourge the forum for small fixes.
