No. I'm really not and luckily I had the last update downloaded still to check for myself and they end in the same spot.
So you think everyone who downloaded the update from here and played it is just having a fever dream?
They aren't, they just did zero things to see what the issue might be with an unofficial leak they got from a pirate site and constitute a prime example on why some people should not be allowed to get their hands on potentially buggy early access versions...
Something I found out from a few tests. The ending screen for 0.8 is coded like the one from 0.7, so any save made
on the ending screen will act as if you had already reached it and end the game, sending you back to the main menu. Call it a bug or an error, shit happens. I originally replayed a bit, so I didn't even notice.
Starting from any earlier save or rolling back gave me no issues and I could play the update from that same downloaded version.
This is what happens when people download unfixed early access leaks instead of official releases and don't give it any additional thought.
Edit: I did rollback quite a bit, so to safe anyone having this issue might want to try the earlier save thing and skip.
