So after the big update, I've found that none of my characters can equip muskets anymore, be they ones that I had in my inventory previously, or new ones purchased from a shop. One of my characters has the required martial weapons feat from his dual class to fighter (started as rogue), and another has martial weapons from barbarian yet can't use them either now. For both it says they lack proficientcy for it, but they both clearly have it.
This is happening with all variants of musket too, be it the ones simply titled Musket, or ones titled Musket with Bayonet, and even one of my characters that has a custom DM crafted musket.
Anyone else having this issue?
