They are freaking out thinking that they might have spent their precious resources (and many of them are low-leveled) when there was a bug that made no mythics drop. Some of them are not aware of the forums, and even I didn't know it was just a visual bug until you just told me (thank you! ). I was looking for official answers and only found that players should try reinstalling, and they didn't get any results by doing that.
Anyway, if that's only a visual bug, good for them. By the way, Iif they did get Infernus (I think one of those ppl freaking out did), does that mean they can't use/trait them for now?
