Gotcha. Definitely a refresh bug then. Sorry about that. :(
No need to apologize, I think Stem/Nyx/Arm is wonderful software. Very useful, thank you (and all contributors) for writing it!
Ahh, think I know the issue. Nyx requires the copy of Stem from its git repo too...
SUCCESS!
Nyx updates the circuits page, the data is in-sync with tor-prompt and seems to be correct.
Thanks Rob! And glad to hear it's working!
