- In the last year we have encountered an increasing number of problems where an asset is processing it's bulkdata on an async thread when it is garbage collected.
- This is caused because we detach the package's linker in UPackage::BeginDestroy but most async asset tasks are checked in UObject::IsReadyForFinishDestroy, meaning we can have async work trying to access the bulkdata in the package file up until UPackage::FinishDestroy is called
-- Usually we try and fix this problem by preventing packages with outstanding async tasks from being garbage collected, but support for this is not universal and can lead to the above problems showing up in various commandlets.
- By moving the detachment of the packages linker to UPackage::FinishDestroy we should be able to prevent these problems in all cases.
