gdb was what made the difference, i had removed members before.
The error was having a blueprint struct sharing the same name as the c++ struct.
once again still starting out.
For reference all i did as debug was.
`
- cd /UnrealEngine/4.19/Engine/Binaries/
- gdb UE4Editor
- set args $MyProject/$MyProject.uproject
- and look through the log till conclusion`
Guess i skipped that at A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums
Thank you.
