No Meridian Flip since update

Prior to the firware update, I had no issues with the meridian flip function at all. I've used the feature twice since the update and both times it did not work. Any suggestions? Please help.

I wanted to add some information about what happened. I just got my ASIAir Plus in April. I've used it about 5-8 times before the firmware update and asked it to stop 5 minutes before meridian, and wait 15 minutes after to flip. It worked every time. It flipped, took the remaining exposures, then went to home and shut down.

Since the update, it hasn't worked with those settings at all. The night the firmware updated, the AA+ pretty much didn't do anything other than shoot subframes. I found the telescope all the way around into the RA stop. The full 5 hours of exposures were saved to memory, which included exposures about two hours after the flip should have occurred. This second night, last night, the imaging stopped prior to the meridian, but it didn't flip. I found it once again against the stop. So it did stop function of the camera prior to the flip, but it didn't flip, nor did it do anything else. Of 5 hours of exposures, I got 2.5 hours.

Could you upload the log in the ASIAIR APP after the problem occurs next time?(About -> feedback)

I didn't know there was a log. I will try that.

For today, I woke up this morning with the telescope in the home position, so I was hopeful. Last night I changed the settings to stop 5 minutes before meridian and then wait until 15 minutes after.

However, when I checked my images, it shot images all the way up to what I am guessing is 5 minutes prior to meridian, then stopped taking images. Somehow it decided to go to home at some point. I asked for 60 subs total, which would have taken well past meridian.

I have it refocusing every 60 minutes with my EAF 5V, however it looks like after the first hour, guiding was bad. Really bad. I use an OAG. Is it possible that the focus routine was off, which caused my guide camera to not be able to pick up good guide stars, which threw the whole thing off after the meridian flip? I know it retries 30 times to center the subject, or something like that. Maybe it couldn't find the object because focus was off and it just quit? What do you think?

The log from last night is attached.

EDIT:
The log attached is the guide log from the night before- the night where the problem initially happened. I went and powered up the AA+ and saw the other logs. It won't let me transfer them to my USB stick- or at least I don't know how- so I took a screen shot(s). It looks like it failed after exposure #3 for some reason and just quit. I'll post the log here in a little bit once I get the screenshots off my phone.

Okay, had to wait through an Android update, but finally got the log. I had to take a screen shot and then combine them in photoshop, so it is an image. Any idea why it would fail? It failed and then shut down. I assume it is programmed to do this for a reason. What happened?
