I was able to contact Steam to remove the 72 hours restriction, so here's the hotfix.
Save file is compatible (some of the fixes will only appear for newly spawned items or at new game)
Bugfixes
fix - Small superchargers cannot be detached from V8 and V12 engines
fix - Cassette player can eject cassette that has been already ejected
fix - Brickstop camp keeps spawning cars after load game
fix - Seed interact prompt is not visible
fix - Tower of terror ladder too short
fix - Cannot sleep when fatigue is disabled
fix - After death player can still use bandages, first aid kits
fix - Boss music plays forever in peaceful mode
fix - Boss UI is forever visible in peaceful mode
fix - Selling liquids to merchants stopped working if player tried to sell other items in the "liquid sell" crate
fix - If player cancelled sleeping, UI remained on screen
fix - Engines and radiators lose physics lock after load game
fix - Sanity Bat and Grimhound codex were mixed up
Changed
changed - Disabled buggy fall damage for now
changed - Removed minimum tiredness requirement for sleep
changed - Cars now automatically detach bumpers when trailer is attached (rear bumpers cannot be used when towing, it gets in the way of the trailer causing physics bugs)

changed - Increased Black Juggernaut HP to 6000
