Sale 2: There's a missed movement to STN here seemingly, RedTornado sells it and receives 115k 39.88ref, and then Derpina pays 129 to the same bot. First movement is a bot dump, but including the 129k STN pickup as it's own sale as well.

Just putting it here to show I looked into it, but looks like either bulk buyout or scam movement, full one way dumps then listed on MCS

Sale 2: Untrace STN pickup, he dumps his PE Tundra to acquire presumably, but would be invalidated since he redumps in Sale 3 anyways
