The first problem is that the extension headers (including a fragment header) are not added to bytes at all because it's not seen as a header or payload. These should've be added to the header (as extension headers are of course part of the header). The next problem is that several bytes are being overriden, namely the bytes at index 67, 68, 75 and 76. This happens because the captured packet was detected as UDP payload, which was mostly OK, but it was a fragmented part, so this shouldn't have been parsed as an UDP packet. As calling .Bytes updates the calculated values (including the length), these bytes were overwritten.
Keep in mind that packetnet always uses and overwrites the original data (the passed in byte array) for performance reasons. If you don't want that, copy the byte array first.

That looks great - thank you.
Will there be a new version of the NuGet package published? Because that's what I and my users depend on...

Yes, might do #102 before NuGet push though, so please give it a try first.

Understood - no hurry - but see my comment in #102 too.
