Hello. I have had similar problems. I will play with it and rrything com out perfect, then I wait for a perfect sunset, set it up, come back and find out it took 5 or so pics and crashed. The only, only combination I have had luck with is leaving it on normal mode not airplane, settin it 15 secs apart and turning autolock to never. But like I said even though I have a higher success rate with this, it will still crash when I actually leave it for a cool time lapse.
