So... When is anyone going to mention this? Heavy machine gun perks go invisible on bonds. Meaning you can't choose machine gun reserves if you didn't already have it selected before opulence. The entire perk goes invisible inside the game, making it impossible to choose. If you switch from machine gun reserves, to f. Ex. Rocket launcher reserves. The bond is officially broken, and there is no way to choose the machine gun perk again, because it dissapears. Needs to be fixed asap.
