Hello there!
I have finally unlocked Tier I on my playthrough and finally unlocked specialization. Problem is, even though the sniper and the grenade launcher both have got ammo when first equiped (6/1 and 2/0 respectivelly, if I recall correctly) the crossbow is at 0/0 and doesn't drop ammo. I have read the instructions and killed enemies under status effects and nothing. I've seen some complaints about an issue with special ammo drops on threads from last year, but none as recent as mine.

Can someone please help me?
