When I am in the garage and I select my old mechs, it shows me the weapons that I previously owned and the weapons that I haven't bought, still available to buy. Totally normal, right?
However, whenever I click on any new mech from the update, then I click in their weapon selection (which they obviously only have one). Then if I go back to any of my old mechs, it removes all the weapon selections as if they only have one weapon available like the new mechs. The only way to reset this back to normal is a full restart of the whole game. Kind of frustrating, but avoidable.
I just need to remember that the new mechs don't have additional weapons and to never click on them. I still figured it was worth posting though as a bug.
