How to resolve grid warning when location is distant?

HI there,

I flew a mission to gather several thousand photos for a large parcel.  The mission is a 'normal' mission but I may have set some of the parameters too high, but wasn't sure how to resolve that mid-mission amongst the ten (or so) flights.

I thought "no harm, no foul."

I received the error, below.  How do I approach resolving this?
