Edit: they appear to have revoked the compatibility statement on their patreon page. I did not see that. However, they worked for me.
Yeah, DC did contradict himself within the same post. One one hand it says in bold letters "
(OLD SAVE FILES NOT COMPATIBLE)" on the other hand he writes just a few lines below:
"Due to the major changes at the start of the game, you may encounter issues. For best results, load a save from the MC's bedroom or map, and not in the middle of a quest.
We strongly suggest starting with a fresh game."
I mean, there's a clear difference between "not compatible" or "you may counter issues". In the end it's certainly not the most satisfying situation, but I'd guess it'll get better and better over time, given that 0.19.5 saves did actually work to some degree.
