So my wife already owns resident evil 2 but the 2/3 combo is on sale for 15$ as opposed to 3 alone being 40$. When she tries to purchase it it says she can’t because she already owns 2. This doesn’t make sense because she just did the same thing buying the 4/5/6 combo pack which worked even though she already owns 6… any thoughts or suggestions?? Thanks in advance for any help!!
