I played through an earlier version, not sure which. Can I fuck Roxxy yet?
Awesome! Too bad I uninstalled, I'd imagine my save file is gone. Oh well, good for another playthrough I guess. Are here any diverging quest lines where I can miss any content?
You played an earlier version from before the Roxy update, and mention that your save is probably gone... One of the most repeated things in this thread (aside from "the two sides" bitching and sniping at each other) is the issue of
save incompatibility.
You'd have to start over again regardless of having a save file from your last time playing.
This is literally the only Renpy game without save compatibility.
This is still a game in development, and that is a common issue with many games that are incomplete, and across different engines, depending on what changes between versions.
Think of it like playing a released Bethesda game.
For games specifically made in Ren'Py though...
-Sister, Sister, Sister had terrible save compatibility. That was down to the combination of each version reading saves from a specific location for each individual version, and the horrendous bugs that would occur (and still do in the vanilla version).
-Superpowered has historic issues with save compatibility, where it often would go straight to an error screen and have to quit.
The recent 0.30 release is the first one that absolutely requires a fresh start, due to changes introduced in it.
-A Town Uncovered also has historically had compatibility issues with saves between versions.
Unfortunately, your hyperbole only makes you come across as petulant.
