For the 1.8 bugs, yeah.
The big issue is that we can't access jack.qsp to check/fix it, but those are really, really minor things that can be fixed in matter of seconds, so don't worry about this at all.
For Gloria/kiss scenes, it's probably just what we said; an error in the code; but in ALL of the Json files of the slaves... If you have means to correct the whole lot, and not have to manually do it (I have no idea how it works), it should be simple enough too, so I'm not worrried again.
For Isabella.... Yeah, this one is havier; I have no idea what went wrong. It's also a little bit more of a pain because without a good assistant at first, you are far slower and less efficient, making it harder to actually "try" the beta more, other than in sandbox/patrician mode with a random assistant. (so at least, we know it's Isabella really, and not all assistant that bugs out, that's something I guess!)
And finally, about the 1 image scenes only.... Well... That's something else. I mean; I don't care that much myself, but it's a bug and I kinda want to try to help fix it, but yeah, no idea what went wrong there.
Don't let that take you down!
We can already see a LOT of improvement, so take your time to finish the project, and it will be fine!
