'Launch' to windows displaying OLD game build?

Not sure why this is happening, since I have launched, packaged and deployed many times before.
I have recently made a number of changes to my map design/game mechanics, and wanted to try the game out to view HUD elements with the Oculus Rift.

For some reason an old map version is shown ??

No idea why!

I’m having the same issue. I am using Unreal 4.9.1. Everytime I launch to android, it launches an older build. When I play in viewport, I have no problems. Any updates for this issue?
