VR returns to Oculus Home at Level Change

Hi everyone,

I am beggining to link the differents maps for my VR project. Yesterday it worked just fine. Today I have been having issues when loading a map, it freezes (normal thing) but with the Oculus hourglass on the screen, after a while, I am taken back to Oculus Home which fades back to UE4 and opens the map I was targeting.
I thought perhaps it was due to the complexity of the map I was opening, so I tested it with an empty map but still had the same problem, bouncing to Oculus Home and then back to UE4, even with an empty map.
I restarted my PC, cleansed my cache and still having the same problem. Something must have changed between yesterday and today but I can´t come up with the idea what may have caused this. Any ideas? Thanks!!

It does have to do with Optimazation. I delete some elements that might be consuming too much GPU and it worked. If I open an empty map but the map I am leaving behind is complex in terms of graphic memory it freezes the editor and Oculus client takes it as if the VR Preview was closed thus taking me to Oculus Home and then back again to the editor when Unreal gets back online.

I have been encountering the same issue. Recently moved the project (today) from 4.17 → 4.18.
Issue is not occurring in the 4.17 version of the project. Issue only happens when playing from in editor.
