The 'sleek circular arm quiver' from Jhiskar's Provisions (Hollow's Eve, this year) appears to be flagged to not hold crafted bolts. The message I get is:

"The arm quiver is not designed to carry anything like some ice-adder bolts."

Store-bought bolts from Milgrym's don't work, either. The e-pedia page is also tagged indicating the quiver seems to only hold arrows.
