Lately, I've been noticing a delay between when a Warp Effect plays and when the remote user disappears. Usually the two events are synchronized within about half a second, but I've been seeing occasions where a remote user's warp effect plays, and then they disappear about 1–1.5 seconds later. I'm currently unsure if there's a difference between warp effects that play when travelling versus when the VRChat client is closed, but I did notice the issue with one user when their client unexpectedly closed.
