The digital game retailer has not clearly explained how the hate symbols made it into an email, but apologized for the "unfortunate visual association."
It sounds like they knew the most obvious one, from the first apology. Though they did leave that in anyway (emphasis added):
What was displayed in several devices as doppelrune is out of our control. ᛋ was displayed as ϟ on several devices (might display for you differently here as well just letting you know). We should pay more attention to checking it on a different systems and devices. I also recognize that placing two such runes next to each other could create an unfortunate association with symbols used by the Nazi regime. This was noticed before distribution, and out of respect for local sensitivities, the material was not sent to the German community.

“We noticed it was some nazi shit but we did it anyway, except in Germany where it’s illegal.” Pretty wild defense.
