The bug showcased is one that has happened multiple times over a course of weeks where when i am playing one of the characters from the rift pass their model begins to break and swing about.

i was playing taurie with the new outfit of hers from the prem rift pass and when i got hit her cape started flinging everywhere and even after i got hooked it still kept going

Ardent Believer skin for Taurie Cain is bugged. Its glitching around the player.
