Well, so far, it's been 2 days since I sent a help support request and (shockingly) no response.
Although, I did notice something interesting. I tried to look at 7 days to Die on my girlfriend's PS store, and the game on her store says £32, and when I went back to mine to check the price, it's saying £24. But here's the problem, is the £24 due to the discount? Or that I have PS+?
Hmm~...
