Hi Kevin,
 
I hate flooding the list with big messages,  but here is a more complete status:  Nothing is reporting out-of-sync that I can find.
but the attempt to sync links still fails.  Here in order are:
 -Definitions
 - Log links for the three physical devices
 - Audit - fails
 - Sync - fails

Here are the mht definitions:

INSTEON_SWITCHLINC,       28.F5.5C,     l_front_porch,      All_Lights|Outside       #Front porch           28.F5.5C 2477D    R7.2 3913 (Load)
INSTEON_KEYPADLINC,       22.92.24:08,   l_back_hall_bH,    hidden                   #Hall Button H: Night scene

# Scene for night mode
#              name,                 device,          cont, resp, on_lev, ramp_rate
INSTEON_ICONTROLLER, A5, night_mode
SCENE_BUILD,  night_mode,           l_back_porch,       0,    1,     20%,    0s
SCENE_BUILD,  night_mode,           l_kitchen_window,   0,    1,     20%,    0s
SCENE_BUILD,  night_mode,           l_front_porch,      0,    1,     20%,    0s
SCENE_BUILD,  night_mode,           l_back_hall_bH,     1,    0,     20%,    0s

The actual linking works correctly.   Button H will toggle the 3 devices between off, and 20%.  Just confirmed that it still works.

Both devices are in-sync with healthy link tables:   Here are the Log Links:

I can't see the message in the snippit you provided, but it looks MH is reporting a problem with (Audit) Sync Links because MH was not able to successfully scan the link tables of the following devices:

$l_front_porch,
$l_back_hall_bH, 
$night_mode,

That last one looks like a scene, which may be out of sync simply because it is a scene controlling one or both of the prior two objects.

So, run the "Log Links" voice command on each physical device listed above.  It will print out a message in the print log.  I suspect it will say they are out-of-sync.  If you see that message you should run "Scan Link Table" on that specific device.

If the scan completes successfully, MH will have an accurate understanding of the state of these devices and you will be able to run (AUDIT) Sync links successfully.
