4.15 Package game cannot find HUD BP

Strangely, after upgrading to 4.15, packaged games seem unable to load any HUD BP specify in the included folder.
We didn’t get any error while compiling the package file though. It only break after we try to start the built package game.

Anyone got the same similar issue here? I didn’t use nativized or what so ever, flicking that on didn’t help much either.

Okay, I’m wrong, it’s not just HUD Blueprint. My 4.15’s packaged game not cannot load any included Blueprints at all.

Anyone got the same problem?

Ouch… I found the problem. It seems that UBlueprint is removed and replace with UClass.

Dang… That’s major work converting everything for us.
