I usually don't complain about visual bugs because I play on the low Graphical Settings as my PC is a chariot. But it happens on my end as well: If I use the ability, it displays normally, if I see someone else using it, the sabers simply don't spin, but his stance and the sound he makes show that he's indeed using Unrelenting Advance
Unrelenting advance is so bugged I'm amazed anyone even uses, in GA all it does is get you killed. Saying its a visual bug is one thing but I've found a lot of the time it doesn't even connect with enemies your standing on top of.
