In the details view select the component and then move it around, the print relative location is wrong
This bug prevents quite a lot of things of being possible with construction scripts. Mainly anything construction script that should also be editable in the map does not work because of it.
8 years later, and this is still an issue.
Any type of variable in an UActorComponent used in the AActor it’s added to will always use the default value in the construction script, and not the instanced value.
