<p>I now have proof that this is happening at a non-trivial frequency on the currently live mainnet, independently of my experimentation with rust.</p>
<p>I have compared the serialized bytes for given <code>OfferPayloads</code> with unique hashes but same <code>id</code> as they were received from the network (this means they were serialized by a java process,  <em>not</em> re-serialized in rust code).</p>
<p>In the time frame I observed out of 52 <code>AddDataMessage</code> that contained <code>OfferPayloads</code> with unique hashes 13 were actually duplicates with the same <code>id</code>.</p>
