So I have my Telescope setup on my balcony. I can see about half of the nightsky from east to west. 
yesterday I took the whole setup, without dissasembling it, down to a different spot to photograph the heart nebula.
I did the whole polar aligning routine like I always do and did everything the same as always.
it seemed like the asi air was really confused when I tried pointing at the heart nebula.
whenever I told it to go to the target, it went into the complete wrong direction, sometimes it got really close, it needed to correct a little and went into
the opposite direction of where it was supposed to go. Sometimes I had to watch out that it didn't run into the Tripod. 

after an hour of trying I took my setup back to my balcony, set it up as usual. It just went flawlessly. Instantly went to the right spot in the sky.

I have no idea why there's a problem pointing north but no issue at all pointing south with the exact same rig.

Whenever I had this problem, it was because I turned the mount on when it was not in home position. Turning the power off, manually moving the scope to Home, and then power on, it worked fine afterwards.

I agree.......before finishing up for the night, always return the mount to the home position before shutting it down.  I use the ZWO AM-5 mount with the ASI Air Plus and that is their recommendation.  Also, make sure you have your location and time entered correctly and as accurately as possible.

that's weird, as I can recal it was in the home position but I'll try that next time. I hope that works. 
thank you guys

I saw similar issues at one point, and solved it by resetting my scope to home position as well. 
After every session I have then finished with going back to the home position and never had the issue again.

That sounds really promissing. I don't go to the homeposition after I'm finished. so that might cause the issue

When you make a plan session with Asiair, in the plan parameters, you could set the "go back home position" at the end of the session. I have also meet this issue with my last mount CGEMii. 

Hence, now, my first action with asiair is set home position and after, I make the focus automatic & the polar alignment.

Before I got the AM5 I had first a CGEM II and then an AVX. It required more care to use these mounts with the ASIAIR. I got into the habit of returning the mount to the home position between targets and at the end of a session. I still do that with the AM5 mostly out of habit.

I have similar problems with the asiair and both my EQM-35 and EQ6 mounts at times. They just go whack after I polar align for no reason I know of.
I just turn off, put mount back to home manually, turn on Asiair and it works flawlessly.
I assume its because it is a $300 dollar computer that has quirks.
