Pr branch (#2312)

* Adjust checking for callable crew object.

Changes back to how it was being done before.
Fixes #2307

* Fix specific memory reset errors.

When not initiated, the function should raise
the "memory system is not initialized" RuntimeError.

* Remove print statement

* Fixes test case
