Explain my green trap.

So this happened a while back but i forgot to ask. It’s probably not a bug and not really an issue but it stlll makes me wonder,
how did my Daredevil trap tile turn green here?

The symbiotes’ Appetite For Destruction ability converts tiles to green when it resolves. It affected your Ambush because a trapped tile can change colors without being disarmed – it’s only being converted to a special tile that overwrites the trap.
