Hi all,
Just wanted to share my experience with save corruption and possible solution for now.
I am playing on PS5, new character after 2.0 patch, started new game.
Everything was working fine for quite some time (not counting UI bugs or not able to switch to arms cyberware, etc. this issues are annoying but not as huge as save corruption), have 60+ hours of play time on this character.
Finished Phantom Liberty mission when you get Active Chimera Core, picked core up, but didn't craft weapon mod from it and didn't placed it in V H10 mega building apartment.
Wasn't getting any issues with performance in V apartment (I love to go there sometimes to stash Iconic weapons, go to sleep, etc.)
Continued my game after patch 2.01, no issues with saves corruption or performance in V apartment.
But then, suddenly my saves got corrupted, right after mission with Panam when Aldecados changes camp location. I wasn't been able to quick save, or manual save after this mission. Closed the game, restarted, and my saves now corrupted.
I managed to download older saves from ps+ cloud, finished same mission and this time all worked correctly.
But, I was wrong, not all worked correctly.
Now my fps is going down when I am near V table in H10 apartment, and then game crashes. If I am placing Active Core on the table FPS goes back to normal, but if I am saving after this, my save file becomes corrupt.
I managed to solve this (at least I hope), you need to craft weapon mod from Active Core before you go near H10 building, just fast travel somewhere away.
Then you go to V H10 apartment, and place Core on the table (yes, I have mod crafted from Core but I still able to place it on the table).
Save after this, and now everything should be back to normal.
Hope this would help anyone having same problem.
I also reported this to CDPR.
Corrupted saves issue should be fixed in 2.01, if you believe patch notes
