Me and an ally were just outside of the "Faldar's Tooth" Delve in The Rift. Nothing was out of the ordinary.
A couple enemies on the ledge of a hill (Shown in the image) And I used Take Flight (The draconic ultimate morph ability). The enemies were at the top of the ledge, I was on the ground floor. I used it to jump up there and attack, when I am suddenly greeted with "The Rift" Loading screen which only lasted for a few seconds. When I returned..... This happened.
After this for about 30 seconds, another loading screen appeared, and instantly vanished. everything was normal after that. While I was in the "void" I guess you could say, My ally could not attack any of the enemies for a short amount of time. they were stuck in place. After all this, everything seems fine.... We hope. But this is really something that should be cleared up because of obvious reasons.
