So infusing items seems to be broken. For instance I have a 340 shotgun (Conspiracy Theory) & I'm trying to level it up with a rare sniper that I have that is 345. Both are of the same year but each time I try it keeps saying "You Currently have no items that are able to infuse this piece of gear" which is definitely not true as I have 2 pieces of gear I could use, I've unlocked both items & I have all of the required things needed for an infusion. Same thing is happening with armour & all my other weapon types. What gives?
