I think we need to check if the advancement is working in each version. Basically, it should give an advancement the first time you get a wood chessboard in your inventory, but it many versions it gives the advancement whenever you pick anything up (or maybe never). This was reported and fixed as #90 but I think the source of the error is variance in the format (I hope), but either way resulted in an always true or never true criteria.

• Check which versions this applies to
• Fix in each broken version
