Signature Arcs ending when switching sides.

I am not entirely certain if this is a bug or not.

I post here in order to give everyone a heads up on the current behavior.

If you are a 1/2 Alignment (Vigilante/Rogue), and in the middle of a Signature Arc, when you travel to the other side the Arc breaks without any warning.

Example:

As a Rogue, I started the redside Signature Arc.
After the first mission, I realized that I had things to do that would take me away from the computer for long enough to auto-logout.
I went back to the day job I was working on on the blueside, via RWZ.
As soon as I entered Atlas Park, my level reverted to 50 and I no longer had the Arc mission.
It did not return when I logged back in and went back redside.
