For what its worth, here is a bug I ran into and my steps to resolve

I noticed that glass was no longer inserting time into my commits. When running glass status I received No timer appears to be running for '/Users/...': Daemon doesn't appears to be running.

I ran glass start and got the timer started message. However glass status yielded the same error. glass stop had no effect either

When I tried to start the daemon manually I received It appears another Daemon is already running or a previous instance didn't shutdown properly, use -force to force start.

running glass-daemon -force and then terminating seems to have corrected the issue.
