I have tried, unsuccessfully, to purchase the seasonal sidearm champion mod from the artifact several times. Each time, it appears as though it has been purchased successfully but the next time I open the artifact, it is once again un-purchased and the point to buy a mod has been returned. This is not game breaking, but I wanted to see if anyone else is having this issue. I am on PC, and have not had any other egregious glitches this season. This is my first post, so apologies if this is not formatted correctly.
