As per the title, I am on the most recent version v2.03b and after roughly 8-12 hours quests no longer accept items for progression, IE item exists in hotbar, and can be moved around, the quest doesn't complete. Exit and reopen the game, move item(s) around, and quest completes.

Not a massive issue, nor can I find any logs being generated that would state what is causing this, but it is some odd behavior.
