Are you using Level Editor beta feature in the game properties? If yes, simply roll back to game opt out of anything and the game will read your save progress.

yep i just figured that out

The save in the level editor branch use another save file to avoid any permanent problems until we are sure saves are compatible between both versions.

I tried running the game and it wouldnt load up, i restarted my computer and tried again, this time it loaded but i have no save file, im back at level one?!?!!?

Can you try to verify the game files to check if some of them are corrupted. I would also need to check your log file to see if there is an error. You can also send me a zip of your save folder and I will see if I can I fix it for you.

Log file:

• On Windows: <game_folder>/znt_Data/output_log.txt
  
• On Mac: ~/Library/Logs/Unity/Player.log
  
• On Linux: ~/.config/unity3d/NoClip/Zombie Night Terror/Player.log

Save location:

• On Windows: %userprofile%\appdata\locallow\NoClip\Zombie Night Terror
  
• On Mac: ~/Library/Application Support/NoClip/Zombie Night Terror
  
• On Linux: ~/.config/unity3d/NoClip/Zombie Night Terror

I lost all of my saves too. What can I do to restore it?

this happened to me ages ago and i seem to remember the developer helping me in some sort of special way, try to get in touch with him, cool guy, great game, make another one

Hey, you can check the post just above yours and check if there files in the folder, if the save file is missing or corrupted, there should be a backup but you might lose a bit of progression, however if that is the case, the game should automatically load the backup. If there really is nothing, I can send you a save file with all the levels unlocked and you can continue from the level you were in.
