Check mark button isn't clickable after I cheat a Vampire's Level or Powers

@crinrict  I don't think so? I'm not very experienced when it comes to saves and all that so I don't mess around much with those. I can only share an attached screenshot of the saves that would correspond with the save I played when I cheated the vampire level. I don't know if any of the versions would serve as backup or if they would all be affected to be honest.

Any suggestions?

@vicucha_sc   Hello!  Thanks for sharing that image.  It shows that you do have several versions.  I believe @crinrict was referring to a backup that you might have created manually?   If you haven't made any manual backups, then there is an in-game recover save option for those that you showed in your save folder.  When you launch the game, you can choose the Load Game option to see a list of saves to load.  In that view, there is an icon to click to Recover Save.

Clicking that button shows you the last five auto-save points.

Then you can check the time and click Recover on one that possibly was before you made any changes.  When you recover a save, the game will generate a save that uses your saved game name and also adds "recovered" at the end of the name.  This way you can test that save from before you made any unwanted changes without losing any progress in your current save.

The checkmark still works for me after using that cheat. Make sure you've assigned ALL your weaknesses. The checkmark will be grayed out until you do. I had to assign 4 weaknesses, for instance, to make the checkmark available again.

@vicucha_sc    Regarding the check mark issue, please check if there is a weakness requirement.  Each Vampire level requires you to add a weakness.  Look in the lower right corner of the Vampire Powers window.  Here my check mark is not available because I haven't selected 1 weakness.

If that's not the issue, do you use any mods? It's probably a good idea to test the game without mods.  Just move the mods folder out and delete the localthumbcache.package file located in the Documents / Electronic Arts / The Sims 4 folder before opening the game for testing.  You probably want to create a new game for testing so you don't make any inadvertent changes to your current save while testing.

If it's not a mod issue, then it could be an issue with the order of adding the cheats.  Cheats can be unstable, so it's good idea to add level-up cheats in the order in which they would occur normally in the game.  You can see the steps I recommend for leveling up a vampire using cheats by clicking the spoiler below.

I hope this helps!
