Unable to interact with Unique chests, Skill Point statues and Health Up statues

So someone, I think on reddit, suspects it has something to do with a flag related to the lyrium dagger, which is the requirement in common to interact with the inactive objects, after noticing that the loop on the end of the dagger no longer appears on at their character's belt, and I've checked my own and seen it's missing for me also. Other lyrium-dagger functions (i.e. for the companion skills) do continue to work, though.
