It seems like I've greatly under estimated just how hard it is to implement Steam's inventory service...
Like many things I've coded, nothing works how it's apparently supposed to, clearly I'm doing something incorrectly but I can't figure out what exactly that is.
I'm not giving up on it but I know delays drive people away so as unfortunate as that is, I will only be releasing it once I'm 100% sure it's working as intended. I've been trying to rush it to meet my deadline goals and in that process I've glossed over things and made a nightmare of code for myself so I will stop doing that and start over with the other Steam API implementation since clearly this one isn't working and I need to stop wasting time with it.
As my name suggests, I'm nowhere near an expert in C# or C++ which is what Unity and the Steam API use respectively. I will try harder to get this functioning as it's obviously possible, I just have to figure out how. I hope those of you who have wishlisted can understand that I am doing everything I can to figure this out and I hope the next update will be an announcement for the full release!
