@savanahphillipHave you put the guitar down at home then readded to your inventory?
Replaced the guitar with a new one?
Deleted the Thumbcache then repaired?
If that offered no easy help.... Sadly the general troubleshooting would be your best bet to see if you can find the problem;
If you have removed mods already... delete the thumbcache and using EA APP do a repair.
If still not working correctly... you need to remove all mods / trays / saves to desktop or rename them (see below ) then delete the thumbcache again, repair again and start a new game with a new test sim.
Then you can add mods back 50 / 50 until you find a culprit.
Then your trays and saves.
OR
~Close the game
Rename Documents\Electronic Arts\The Sims 4 to Documents\Electronic Arts\The Sims 4_Old
Repair the game
Start the game. All your content will be gone now as the game created a new folder. All your saves/.. is still in the old folder so not to worry
Start a new save game
Check if you still have the error
Report back with your results for further steps on how to get your stuff back.~ quote from crinrict
