Loading models within models

[eluser]bhogg[/eluser]
With some debugging it's definitely hitting line 184 of Loader.php, and being added to the CI instance->sessions_model, but is not visible from $this in the model when it tries to access it. Loading it ahead of time does the trick at the cost of having to auto load nearly everything.

If I find anything else out will post here or will just upgrade to CI 2.0 which may have this resolved
