I've come across this same issue just now. I have both masks placed, but the round glasses will not give me the option to place. It's like the game thinks its the wrong item database name. Currently do not have the raybans to test with.
Bit older thread now, but when do we expect to see the free copy of the game, std ed, key? I have seen and given away the 7-day trial keys to people, but I do not know when the key for std version of the game will be given? I purchased the game in May, well before the August cut off. Thanks.
