1.21 BUG Ship stuck trading with station

[Aranov]

Version 1.21, started 1.0

Got a freighter that seems stuck trading with a Paranid Trading Station, been sitting there for at least 30 min.
Wasn't watching it that closely, since I just tell them where to go and what to buy and sell, so I don't know what happened.
Can't cancel the trade order or get it to undock.

The ship in question is "TIS HF Gold Mountain", a Selene model, in Pious Mists II.
It's stuck with a Spaceweed order, Save is in sector with the ship, with the player on a Behemoth Vanguard.

Anything?

Been playing since I posted this morning and it's still there, still trying to sell the Spaceweed and refusing to undock.
