Summarize your bug I have this now for over 2 months, pretty much. I can not equip the 50 mm Cannon even tho it should be unlocked... I have made at least 150 of those "kills/assist/etc" in the past 2 weeks with it, but still nothing.
How often does the bug occur? Every time (100%)
Steps: How can we find the bug ourselves? I have no idea?
What happens when the bug occurs? I cant choose the unlocked weapon because its grayed out, even tho I have over 150 kills/assits etc...
What should be happening instead? Able to choose the 50mm Cannon because I have enought kills etc...
