Calcium overwhelming quest - 123/123 but won't complete

[StoneMan3D]

Hi all,

With the announcement of Grounded 2 I wanted to go back and finish off the 4 achievements that were added post 1.4, including BurgL quests. I've completed every single one, but for some reason number 96, Calcium overwhelming, for collecting all milk molars won't complete. 

I collected all the milk molars previously for the 100% report card prior to these quests being added, so now the quest just shows 123/123 with a completion 'tick', but won't actually clear from my quest list.

Any advice on what to do? I've seen online that a few people finished it by collecting all the new ones in a NG+ run, but given that I've already run around getting 123 of these guys and the new ones are all randomized I'd really rather not do that

Noticed the screenshot was an old one where I still had outstanding quests. This image shows this is the only remaining quest, and cannot be completed despite showing as 123/123.

I’ve run into the same problem. I went back to the first Grounded game to get the new Achievements out of excitement for the new game and found out that this challenge was bugged. Kinda put a damper on my personal hype. 
 

I finished all of the other challenges thinking that maybe it would think it’s complete once I finished everything else and the achievement might still unlock. No luck. Tried resetting the game and Xbox as well. Really wanted to finish this before NG+ and don’t want to look for all the Milk Molars again. I guess I’m done for now until a patch is released.
