Application Package and MY_helperName

[eluser]coldscooter[/eluser]
I'm using a 'package' to hold shared resources between two apps i'm running on the same CI deployment. It's great for sharing libraries, models and helpers.

But it won't recognise when i put extended helpers/models in there (MY_helperName). Which means i'm ending up with lots of duplicates of extended helpers and classes in each app.

Does anyone know how to fix this?
