Packaging Errors (Seems like an Engine Issue)

Development Platform & Builds

I have tried everything related to this packaging error, and it is still the same issue. Do you guys have any idea?

I have tried: Reimport, Rename, Migrate it from GASP again, Validating, nothing worked.

Maybe this is an actual Engine issue?? with 5.6

that might mean that you’re having a node calling a function that should not be called during packaging.

it’s hard to know which, but i’ve done things like that when adding components on constructor for example.

keep in mind that the constructor is called during cooking too.
