Packaged build + oculus rift + sublevel = black screen

I’m using 19.2 & Rift CV1 and got the same problem … This aint work… I found that maybe it’s because the game state didn’t change to InProgress correctlly, which caused no ‘Load End’ and ‘Splash Hide’ got processed.

Here’s a part of the log file:
