Permanent_records and Rails Engines failure

[Anuta555]

I have a model Productable that has_many products with dependent: :destroy
I have a model Product in both the main app and in the engine.
I have other models in the engine that belong_to Product

When my productable gets destroyed, product gets destroyed too - both hard deleted.
However, product has deleted_at column.

I have a before_destroy hook on the Product model, which triggers an event in the Engine, that in turn, removes something that belongs_to the Product in the engine.

This event from the main app the Product model, for some reason, is triggered twice - and that's the error. Why is the before_destroy hook on the Product is triggered twice?

Removing the gem eliminated the error - so it definitely has something to do with how the gem works with the Rails engines.
