Efex83: When i level up, more and more frequently, unlocked equipment shows with an "owned" tag, indicating that i have it available.
A screenshot of the "unlocked" pop-up window with an "owned" tag on it has been shown here.
It may be quite irritating for some though it must be clear that they had no previous chance to buy that equipment. Thus, WGT displays an impossible situation, and players may be deceived to check in the Pro Shop and buy the equipment while they think they own it already.
IMHO, another twist of greed :(
