I seem to have hit a dead end and the hint is stuck on giving me grave and mob, but nothing coming out of it. Is this is a bug, or would this be the next step but the demo won't let it go further?

Completed the game and unlocked everything: https://steamcommunity.com/sharedfiles/filedetails/?id=3063794075 1. Counter displays 186/184 2. I didn't get achievements "Skills and Spells I" (2 objects in Skills and Spells group) and "Skills and Spells II" (8 objects in Skills and Spells group) 3. Three items are still displayed in a list even with the option to hide unusable items on (see screenshot)...

This is included as part of Next Fest, but doesn't seem to have a demo

I notice it's possible to discover the same character, like the Warrior, OR the same item, like Poison, using different combinations. Would it be possible to increase the "Level" of these things for every different combination discovered? Like, put a number in the lower right of each picture with 1 to X for each one found, just increasing with every new one? I think this would add a little more to the game. I see these same combinations, and I wonder how many times I've discovered it. Well, a Poison...
