I just posted this suggestion for Catan: https://boardgamearena.com/bug?id=82568
When you accept a trade, you can change your mind and cancel it if it hasn't been done yet.
When you offer a trade, you can also change your mind and cancel it.
But if you click "reject" on someone else's trade, even if accidentally, you're stuck - you can't change your mind.
The game should add an option to un-reject a trade you clicked reject on.
If you agree, please click on the link and vote for it (click the green thumbs up at top center).
