Hello, everyone!
I have issue on truffle console (or unit test). The issue is like following.

Case 1:
contract A - method m_a
contract B - method m_b
Truffle console : call m_a and then call m_b

Case 2:
contract A - method m_a
contract B - method m_b (call method m_a in this method m_b)
Truffle console: call m_b

The result of Case 2 is different from Case 1.

I think in Case 1, calling m_a does not affect to the blockchain network

could anyone let me know the reason?
Thanks!
