This issue affects sprinting and teleport delay, and causes players to slow down noticeably for periods of time. It was first reported by our Stuntrunner community, but it affects all activities. We've seen strong and repeated evidence of this issue, but it remains very hard to reproduce reliably, and therefore very difficult to fix. Any information players can provide about how to reproduce the issue reliably would be super helpful, and we'd really love to get this one fixed as soon as we can.
