Di2 drops onto small front cog!
Twice its happened now on my cube c62. The di2 front cog suddenly drops onto the small ring. Under load when hill climbing the chain seems to suddenly jump onto the small front cog without me touching the shifter. It happened at exactly the same location on a route I take. The rear cog is close to the point where it will auto shift the front, but the thing is I haven't touched the shifter and bang suddenly the front drops down. Any ideas?

I am not sure. You have no chance.
