I had some connectivity issue, currencies in the right corner were flashing, I clicked legends tab and the new catalyst, to check out her skins and I have noticed that there was a header '30/1' items bought, or something like this, I thought it was strange so I have clicked on a caustic, as I have some skins for him and there was something like '2/1' skins, one of them was a Heirloom hammer, I clicked on it and I cant remember what exactly happened but then I have closed the game, later on, in the evening, I turned on apex, joined a match and to my surprise I was wielding this heirloom hammmer and I still do have it. I am worried that my account is going to be banned but It was just a strange bug.
