HDHomerun prime (using QAM) tuner left in use after channel EPG update?

[Spark]

I can't be sure if this occurred in the older version of NPVR, but, with the newest (3.29), after doing a EPG update for channels, it went through the normal process of doing whatever it is doing for 60 secs (or whatever it is) per channel, but, I glanced over to the HDhomerun, and noticed that one of the tuner LEDs were on.

The update finished, and the tuner LED is still on...which shouldn't be the case, since nothing is recording.
Doing a little digging with hdhomerun_config_gui it appears the last station that tuner was using was 116, and that channel is encrypted.

I overrode it, and turned that tuner off manually, before NPVR had a chance to use it, since I had no idea if it would record, or would it just try another tuner...

Right now, NPVR is recording and that tuner again, so all is well on that side.

Search didn't turn up anything, so, not sure if this is a bug, or a one time glitch or what...

Well, it did it again on EPG update...
in the logs, I see:

So, for some reason, it is locking the channel (Calling LockChannel()) but there is no UnLockChannel() to be found (though, not sure if that is logged or not.)

The problem is, that tuner will still be "in-use" and NPVR has no option to override a tuner that is 'in-use'. The only fix is either run silicon's dust program to override that, or reboot the homerun prime.
