I put out a Flagship on a prior turn. In a later turn, I played Urchin and my opponent reacted with Moat.
The Urchin didn't get replayed, and Flagship stayed in my active area until the next turn.
A turn or two later, I played Urchin again, he played Moat, and the Flagship again didn't activate, but stuck around. On yet another turn, he finally didn't have a Moat, so then the Urchin replayed.
