Ok so, some bugs I noticed since I had a investigation to complete when I finished act 2
You can call the Beast Tide, though that locks you into having to reincarnate since no buttons work after dealing with it.
I dont know if it was because I called the Beast tide, but reincarnating now puts you at 92 years instead of 16. Also, I´m pretty sure some of my longetivity went away, since I was around 1420~1440 and now I´m at 1377 max years. It might be just some kinks of reaching Act 3, but its good to report
edit: Re-doing the call for the Beast Tide, you can interact with the UI, just not with the time since its still frozen.

Another thing I just found
By doing a F5 while on act 2, the longevity went from 1377 to 1334. Importing a save from the same life didnt fix it, but funnily enough, once I reincarnated, it went back from 1334 to 1377.
Edit: Its a lot deeper than I thought. So, the longevity loss is caused by, after completing act 2 I assume, reincarnating manually. Some of the longevity just is gone, as I had received it back after getting the last investigation, though now a bit higher at 1380. Another thing is that it doesnt only happen at F5, by importing a save, on the current life, more of your longevity is eaten, but given back once you reincarnate. Hopefully this help you hunt down the bug
