But not sure if that will solve the issue here.
That's a possible cause. Alignment may fail early because `.xindexes` returns different mappings of coordinates vs. index objects. It's worth checking if after copying the dataset, `copy.xindexes` returns the same CRSIndex object for its ""x"", ""y"" and ""spatial_ref"" coordinates.
EDIT: checking `copy.xindexes.group_by_index()` is more convenient.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1409811164
