Prison Architect Content File Locked
Content file locked always means your snake oil antivirus is blocking the file and has put it in quarantine. Get it out of there and whitelist the file. For anyone wanting to enable privileges for any of the locked security levels (death row, protective, insane sec); I have found a way to edit privileges for any security levels, even the locked ones.
Firstly, you need to open up the specific save's .prison file in notepad or something similar. If you go and open a save file from before that, then create a new prison, your policies will be correct for protective custody, death row, and criminally insane. I've reported this to the devs.
I can't promise that there's a fix, but we'll look into it. Jail keys are everywhere! Mutator options. Help is also available if you can't log in, need to reset your password, or recover a hijacked account.
A fan-run community subreddit dedicated to the games Prison Architect & Prison Architect 2, developed by Kokku (formerly developed by Introversion Software & Double Eleven) and published by Paradox Interactive. You obviously have to do that after the patch is fully downloaded and cloned files modified. It does not prevent the problem from happening again, but it is a fix at least and don't have to reinstall.
Everything was going well with 40 or so prisoners, so I extended the land and added a new cell block to start taking some lower security ones in too. I have recently picked up Prison Architect, for the past few days it has worked fine. However when i wanted to launch the game today, I got the message 'An error has occured while updating Prison Architect (content file locked).
