Quit a few achievements didn't properly register from my cross-save between Switch and Steam.

For example I had to enter the administrative chamber on PC to reister the trophy, I have Poseidon's prophecy of beating Theseus done, I have manged to get Charon's card (I fullfilled Hypnos prophecy, have it show up in the codex), I did the Erebus without the onion, and so on. There are only I think 2 or 3 that I actually didn't manage yet (16 heat trophy, selling a Legendary), but the rest is done and sadly they don't register.

There were quite a few I had to repeat on PC to get the achievement - like the Hermes one or enter administrative chamber.
