That is the weird thing, I cannot find an email receipt. This is so strange, because I know I bought GC3 and OTC together and registered GC3 to Steam right away. I remember because I was super excited that GC3 was finally 50% and decided to add on OTC for an extra $20.
I changed my password a couple of times in between, could that have anything to do with it?
It is strange I cannot find the email and it is double strange that my account name has no record of it.
