The first is just a cosmetic problem. There were a couple items that triggered quest log updates, though I think all the one which caused problems have been fixed. Fix ones include a bottle of water early that the prisoner in act 1 wanted, and the items the alchemist wants in act 2. I'm not sure if this was fixed, but there was a manuscript in act 1 that would trigger the archery quest entry.
You needed to give the key from the lich cave to the imp if you wanted to solve that quest.
