we shouldn't need flag.Parse. The flag is parsed into the variable by cobra.

The flag should be called with a double hyphen --addr or with -a shorthand flag.

Please check that the config is generated with a double hyphen for --addr on skychat.

Then, make sure that is actually what is passed to skychat. It might not be because of some erroneous code.

it's the double hyphen flag in the config. I can't say I'm experiencing the same issue on develop either, hmm
