Initial values for class are lost in packaged game

Development Programming & Scripting
1

After packaging the game at least one BP class, my pawn, loses all initial values. It’s a data-only class and it keeps it’s default values in pie and standalone so works correctly. In the packaged release however the variables hold values inherited from the parent class (confirmed by log prints).
Due to the nature of the issue I don’t know exactly which classes beside pawn are affected.

Binary 4.7.4-2497108. The project is mostly BP with one C++ class.

Hello ZoltanE,

I have a few questions for you that will help narrow down what issue it is that you are experiencing.

Quick questions:

  1. Can you reproduce this issue in a clean project?
  2. If so, could you provide a detailed list of steps to reproduce this issue on our end?
  3. Could you provide screen shots of any blueprints that may be involved with the issue?

I migrated the pawn class to an empty project. (Of course that also carried over two dozen other BP class dependencies.) Sadly the issue is present there too. There is one thing clearly different between the original and the new project: the original one crashes when I hit “Launch”. Here is the crash log:

EDIT: Launch in the empty/migrated project shows the problem just like in the packaged versions. The build configuration doesn’t seem to matter.

I also compiled the single C++ class for every configuration from Debug Game to Shipping.

I tried to make a simple pawn hierarchy in an empty project but of course that works. My actual pawn and the related classes are way too complex for screenshots. I guess I’ll start deleting stuff in the migrated project and see if things change.

Hello ZoltanE,

I was unclear before, when I asked if you could reproduce this in a clean project I meant without using any assets from the project that is having the issue.

Yeah I got that but I couldn’t do it in an empty project. However I’m almost done with a skeleton project which showcases the bug.

Hello ZoltanE,

I was able to reproduce this issue with the project that was sent. I have written up a report (UE-13579) and I have submitted it to the developers for further consideration. I will provide updates with any pertinent information as it becomes available. Thank you for your time and information.

Make it a great day

Seems to be fixed in 4.8.
