Hi, I resolve that problem myself but I cant remember how I did that. Please try these things.
1. Take those "?" items. Sell it. Then save game and restart the game.
2. Those things 95% is DLC items. So we have to go to the DLC maps that contain those items. Like go to Smash Brethren 2 map (Wedding Banquet) item. Then save,restart to see what happen.
If those things wont work. Pls quote me, I will dowload the game and find a way to help 🙂 Hope you happy
