Wrong version of .py used with Pythonista 3.4

[ftourand]

main in file A.py calling function in file B.py (in a different directory!).
While modifying B.py and launching main in A.py, previous version of B.py is called
Pythonista 3.4 behaves like file B.py is not saved (and remains in cache or ram) when execution of A.py is launched

Stop and launch again Pythonista 3.4
Launch main in A.py > the right version of B.py is called.
