Same here.
At one point shortly after the last good savefile all the future saves are deemed corrupt by the game.
This is the last save the game is accepting:
save_22-06-17_09-50-33 _fresh_water to nuclear reactor.save
The last save of the second time I tried playing from the last good savefile:
save_22-06-21_16-56-49 nuke to power.save
Log from when starting game -> attempting to load this save once -> exit game on error:
Player.log
Logs from testing all available savefiles after and including the last good:
Player.log
Player-prev.log
Last 4 autosaves (missing ballpark 30-60 min playtime between save_22-06-17_09-50-33._fresh_water.to.nuclear.reactor and 22-06-21_16-03-23_0336-autosave):
22-06-21_16-03-23_0336-autosave.save
22-06-21_16-18-23_1213-autosave.save
22-06-21_16-33-23_2065-autosave.save
22-06-21_16-48-23_2558-autosave.save
Let me know if you need more info.
Atm I can't play any further since something corrupts the save shortly after save_22-06-17_09-50-33._fresh_water.to.nuclear.reactor
