Epic how he disbanded afterwards, LOL. But seriously, even accidental lots can happen. One time inventory shifted and I got a 25 that an LS mate wanted. He didn't have the 35 so it was no big deal and we've had plenty since then, so it does happen. I tossed the 25 (skadi legs off of AR which we get a ton of) as it was inventory -1 and I'm not interested in the piece as of yet.
Anywho, particularly 35s, because of accidents, I tell the recipients to be the ones to pass last because mistakes happen but it's also the safest bet regardless. I always pass last unless the only person that hasn't bid is the person that wants it. But in reality I prefer they even wait for me to pass just so I can't *** it up either.
Just be more careful and I hope Liara gets her piece next time.
