Other people have complained about it, but I'm not certain how reliable that it.
Look through your inbox for PMs you had before we moved to Huddler, and you'll most likely be missing some old PMs.

Confirming this bug has been difficult, due to the fact that if you send a PM but get no reply, it doesn't show up when you search for it.
However, before we moved to Huddler, I had backed up 40k PMs from vB. So, when you consider that many more were deleted, as well as quite a few conversations on Huddler since then, the total of my sent and inbox PMs now should be over 40k.
But, here's what I have instead:
That's a total of 27,528, well under what I should have.
