Creating a macro that compiles and saves without any errors causes the build to fail when trying to package. This is failing on each platform tried.

1. Download project: [Link Removed]
2. Open up the Macro that's in the Character Blueprint
3. Compile and Save it
4. Try to package the project for Windows 64-bit

Expected: The game should package
Result: The game cannot package due to a build error
