I have been trying to hoard Worm Houses for the "Back to School" quest and I get one every so often from my houses.
I check my inventory to double check that I have it and check the quest to see if it sees it too.
Unfortunately, whenever I leave the game and reload it to play again, I lose whatever worm houses I had.
I only need 5 to complete the quest and I have lost about 8 now due to this bug.
