Hi Will,
I would like to test this out with your file myself, but your link above is redirecting to a 404. Could you make a new one?
Another question - I assume the error you get each time for this file is the same each time you upload:
metainfo error: value changed: ...
storj.io/storj/uplink/metainfo.(*Client).Batch:1118
storj.io/storj/uplink/storage/streams.(*streamStore).upload:239
storj.io/storj/uplink/storage/streams.(*streamStore).Put:113
storj.io/storj/uplink/storage/streams.(*shimStore).Put:50
storj.io/storj/uplink/stream.NewUpload.func1:52
golang.org/x/sync/errgroup.(*Group).Go.func1:57
Is the data printed after the value changed: (e.g. \"ac110.../s0/testbucket/\\x02(\\xa9\\x9a....\\xf3\\xd1) consistent? Knowing this could help narrow down the issue, but it’s cool if you don’t know. In any case, if I get the file from you I can try to help.
