Yes there is quite some new stuff. Do you have an earlier save that you can load by chance? It's been tested by multiple people and it should work. In the main menu it says 0.3.1? Also if it still doesn't work, would be nice to get the save game file over on discord :)
I actually did open an older save but the same thing happened so I am just going tru the whole game again, and I think there are a few new things but not sure, I´ll comment again once I pass the end of the previous version
