Old saves have issues, and again clicking is a terrible way of getting through this game, you'll break your mouse before we get to 5.0. Instant text speed, <skip unseen> and after choices. Since you wanna get to the new content you could leave off skip unseen. There are only a couple real choices in the game as thokai pointed out above.
Other things to note would be that the WifeSpy Hypno is worthless and wastes your time, outside of feminizing Edwin, BBC Mia, and similarly any others you'll see in the Walkthrough app. Generally Fuckstagram is worthless, although in Neto- content I did get a couple prompts to go there from the Walkthrough app.
This is just time saving advice and saves your mouse from wear and tear. To be honest getting to the late game for each path still takes up to about an hour while things skip past. Leave a review of the game, maybe Bloody Ink will do some work to actually fix the intro and early game so it isn't such a massive time sink.
Not for 4.8, 4.7 has one and it's in the first post, but it has yet to be updated to 4.8, and honestly just install 4.7 from the first post and the Update Only from the 4.8 posts, I also did the bugfix in between, but it looks like all the bugfix files get replaced anyway in the 4.8 update so should be unnecessary.
Use the walkthrough app, you should be able to see that the neto paths are subpaths of the cuck path and require step 102ish to get to the choice for Rase/Rare
The installation I did of 4.8 doesn't even have the second bug fix XD. Anyway, it should be the Full one (not sure which of the two is correct there), Bugfix 1, Bugfix Latest, 4.8 update only. I honestly just built it off the first post: 4.7, Bugfix, and then the post with the 4.8 update (update only). Works quite well, although I don't even think the bugfix is 100% necessary there since I believe 4.8 has the same files and you'll be overwriting them.
Here is the 4.8 updates again so that people don't have to go back like 8 pages to get to the posts.
