4.12 Blueprints fail to compile (GenericShooter)
Hi, i'd like to report an issue with blueprints not compiling and loosing their node connections in 4.12 - I tested this with the GenericShooter Example from Michael Allar.
Issue 1: MainFrameActions: Packaging (Windows (64-bit)): UE4Editor-Cmd: [2016.06.02-08.57.32:698][ 0]LogBlueprint:Error: Compiler Error The current value of the ' Target Array ' pin is invalid: Array inputs (like 'Target Array') must have an input wired into them (try connecting a MakeArray node). from Source: /Game/GenericShooter/UI/MainMenu/Widgets/Menus/WB_HostGame
When opening the blueprint it does not show any errors inside the editor and compiles fine. When you open the blueprint and try to add a variable the engine will crash. It is not possible to alter the blueprints, it appears that the changes are not saved.

If this is an issue with an unofficial marketplace asset, you'll need to get in contact with the creator of that asset. It looks like this particular template is only supported through 4.11, so you'll likely need to wait until the creator updates it for 4.12 for it to work properly in the new version.
If you are able to reproduce this same crash/issue in a clean project, feel free to post that information here and we can continue to investigate.
Have a great day
