During cut scenes where characters are probably laying down or sitting, instead they are shown T-Posing. This happens in the Striker's introduction story fight vs the champion for Striker when she is knocked down and in the cutscene for the Striker when she is an infirmary bed (still in the introduction)
This also happens in the cutscene for the Priest when she is in the infirmary bed in her introduction story. I don't know if this happens for all cut scenes since these are the only ones I've played in a while. unknown.png
