Cult of the Lamb is known to have a bug which prevents players from saving their games. This can result in them being locked out of the game. Discord Server users have found a solution to this problem. This wasn't something I did, Sciguystfm posted his fix in the server and I decided to share it here in hopes that others might be interested.

NOT BEING ABLE TO LOAD SAVES FIX

You'll know you're effected by this if you see a red hat to the left of all three save slots, and you're not able to load your save or delete existing ones.

First and foremost, this fix only works if your save file itself isn't corrupted. 

The save file itself can be found at C:\Users\YOURUSERNAME\AppData\LocalLow\Ma*sive Monster\Cult Of The Lamb\saves typically it'll be called slot_0

Easiest way to test whether or not your save is corrupted is to upload your save file to this site. https://pentalex.github.io/COTL-SaveDecryptor/ - [github.io]  If it tries to download a file back, it means you're lucky and your save is probably fine.

If that's the case, the next step is to disable steam cloud saves. 
You can do that by right clicking the game in your steam library, selecting properties, and unticking the check mark labeled "Keep game saves in the Steam Cloud for Cult of the Lamb. 

After that, navigate back to C:\Users\YOURUSERNAME\AppData\LocalLow\Ma*sive Monster\Cult Of The Lamb\ and copy that entire folder somewhere else for savekeeping as backup. 

From there, all you need to do is delete the meta_0 file in the C:\Users\stefa\AppData\LocalLow\Ma*sive Monster\Cult Of The Lamb\saves folder and you should be good to go!

If that works, you'll want to turn steam cloud saves back on. To do that:
- Launch the game, hop on your cult, save and quit.
- Go back to that right click menu, then Preferences, and then re-check that box you unchecked previously
- When you relaunch the game, steam should yell at you about conflicting saves, simply choose the "Local Save" and you should be good to go!


IF YOUR SAVE IS CORRUPTED
you might be able to pull an older save from steam's cloud save history, but i don't have personal experience with that https://store.steampowered.com/account/remotestorage - [steampowered.com] 

Special thanks to Alex and LavaStar235 for the decryption tool and figuring out meta_0 ❤️

My Thoughts

As with all things save-related, it is a good idea make a duplicate of your save files in case something goes wrong. You can do this by simply copying/pasting them into a different folder. This is a temporary fix that we hope will be fixed.
