I can't confirm whether I am recording new nodes because of a separate issue.
The recording of new notes has not been corrected. You still have to spam click any new node several times, then mine or gather. The new node will appear after that.
I can not answer about the other problem because I stopped using Cart_mining, Herbs and Treasure because of the issues(went back to Gatherer). I periodically(after any updates to Cart) will enable Mining to test it, when I do have it enabled my nodes do show up.
