If and how to report strange replies from the server?

Hi,

I'm using the command line client as it is shipped with homebrew on MacOS. From time to time strange things happen like the following:

```
keybase track wyllys
```

Yields a fat red error which ends in `error: (1701 v 1702)`.
Another thing is that a track command can emit a warning:

```
warn: When checking spaetz: BadSeqnoError: bad sequence in root: 2 != 3
warn: Likely this is a bug or transient error; but the server could be compromised
```

From a users perspective:
1) Should I report these somewhere?
2) How worried should I be? (Assume I'm paranoid. How to calm me down?)

Start by reproducing the `keybase track wyllys` and `keybase track spaetz` cases from the issue, focusing on the reported error and BadSeqnoError output. Trace the `track` command's handling of these server replies and use the issue thread for context; done means establishing whether this is a client bug or transient response and documenting where users should report it and how concerned they should be.
