[Quest Help/Bug] Main Story: With the Utmost Care

[TallonOverworld]

If it's an accepted bug then all you gotta do is wait for a GM solution.
In the meantime, check each step of the quest exclusively if it's stuck before you get the heavy warded pot.

1) Talk to Hahasako and accept the quest.
2) Head east behind Burgundy Falls and then south to the bottom of the ravine at 29-25.
3) Use the Quarrying Maul on the Corrupted Cluster.
4) Use the Warded Pot on the Corrupted Cluster.
5) Return to Highbridge and trade the Heavy Warded Pot to Hahasako.
6) Return to Camp Drybone and trade the Heavy Warded Pot to Lamberteint to complete the quest.

I would also check the calamity salvager just in case although this npc is for an entirely different purpose.

Yeah I backtracked the entire quest already as you suggested, as well as checking the salvager; no luck unfortunately.

I'd imagine i'm going to have to wait at least a few weeks before I am even able to play again.
