I did FoxyMast0 but I couldn't get FoxyMast1 or FoxySuck0 to activate. It turns out there were 2 things blocking me. One was I had to do FoxyPhoto8 for some reason even though those threads were mutually exclusive in the original game. The other is there appears to be a Look requirement that isn't shown on the thread board. I had haircut and bathed but needed to wash as well. I tried reloading and just doing FoxyPhoto8 or the washing but it only worked when I did both.
Another strange thing, I went to the Nanny's room to do a Photo event and got the nannySex Punish event. I don't even have the nannySex thread unlocked yet and it wasn't the right day or time either. I'm not sure what's causing it to trigger now since I got the nannyOfficeCam scene of her peeing awhile ago; it was I think the third one I got and I have 11 now.
Thanks for the report, and I'm not surprised that there's a bug in there somewhere. The requirements for the "Teach Foxy" events was really convoluted in the original game, and it took me several weeks to get something similar working in the remake (while having some semblance of the hint system working for those events). There's a hidden thread 'foxyTeach' that pre-screens access to foxyMast, foxySuck, and foxyAnal and checks for the Look requirement. So, officially, you only need Look >= 80 to get the "Teach Foxy" menu selection when you talk to Foxy, not for the actual foxyMast/Suck/Anal threads. But, since the only way to access those threads is through the Teach Foxy menu selection, it's kind of a moot point. So, I've added the Look check to each of the individual events in those threads as well, but that won't show up until I have time to post the new patch.
I'm not sure about the foxyPhoto8 issue. If you've finished foxyPhoto7 then foxyPhoto8 will take precedence when you try to talk to Foxy in her bedroom, effectively blocking foxyMast, foxySuck, and foxyAnal. Could that have been the what happened in your case? Or were you blocked earlier (although it may be hard to tell if you didn't know about the look requirement)?
Regarding the nannySex_Punish event, that's a complete oversight on my part. It's been enabled for you ever since you saw the nannyOfficeCam scene, but you probably didn't enter her room at the correct time until now. Once you've seen it you don't have to worry about it triggering again (at least, not until you watch that nannyOfficeCam scene again). But, I've now put an extra check in the next patch to block it from showing up prematurely.
But, I'm not going to release the next patch until you've finished the game, because you're doing such a good job of finding the bugs!
