When updating a course on the client I get an error given below

To summarise the main problem is that these values should match but they don't
$dstchecksum = d8cb3ec6bc26c32f662261d3d2d8dc4e
$md5 = a561edb99e83851ef7e1b0a8d83161a9

eyeballing the code I wouldn't expect them to. It seems that srcchecksum should be used instead of dstchecksum assuming the value in srcchecksum represents the hash of the files on the server before they're zipped. When trying this it appears to work but the update itsn't copied across.
