Do you have any proper proof of the 32 sale? (Or the stn dump, for that matter.) The fact that this sale doesn't have the buyer (assumedly, Unusual #2 in this case) traced in the history is a pretty glaring red flag.

Even if 29 was dumped for less to stn, it doesn't feel fully appropriate to exclude it in favor of a higher sale in this case.

If you don't have any evidence of either, you'll have to ask dedandrei for proof of his purchase, at the very least.
