Hey everyone! Earlier I made a post about the bug where mutagen slots are completely locked or not working (while skill slots are working fine).
I found a workaround using the developer console. It's a bit tedious and requires several steps, but if you follow them carefully, everything will work properly — it has already been tested and confirmed. Once you complete the process, your mutagen slots will function again as intended.
Note: This requires using cleardevelop, which resets your character to level 1 and clears your current inventory, so follow the steps carefully.
Step-by-step fix:
- Save your game.
- Put ABSOLUTELY ALL your items into the green stash chest (everything you can store).
- Take a screenshot of your quest items inventory! Do not skip this step so you don't forget anything or break quest progression later.
- Open the console (~) and type: cleardevelop
- Restore your level: setlevel(your_level) (e.g., setlevel(12)).
- Take all your gear back from the stash and re-equip it.
- Restore your missing quest items using additem(item_id). Search "Witcher 3 Item Spawn Codes IGN" on Google to find all IDs, or use IGN wiki.
- Restore missing skill points (including those from Places of Power) using addskillpoints(amount) (e.g., addskillpoints(14)).
Hope this helps anyone stuck with this issue! I'm still working on finding a cleaner, easier solution that doesn't require using the developer console.
