Got an error from zsync while updating, stating the server couldn't handle partial content.
Upon inspecing with CURLOPT_VERBOSE=1 I found that it's only the last request returning full content (200)
It's doing that because while the total file size is 243233088, it's requesting the range past it at 243236863.
I'm not sure how to reproduce, here is the log and the version of tools i used.

zsync received a data response (code 200) but this is not a partial content response
zsync can only work with servers that support returning partial content from files. The person/entity creating this .zsync has tried to use a server that is not returning partial content. zsync cannot be used with this server.
See http://zsync.moria.orc.uk/server-issues
Other error? -1
-1 returned
* Closing connection 1
Note:
If I naively limit the final range to filesize-1 in fetchRemainingBlocksHttp(), the update works. It would seem to be a calculation error in the zsync calls, or and error in my generated .zsync meta?
