"destroy a pandoran colony" objective

Help, I cannot find any pandoran colonies to destroy. I ignored this objective instead doing all the other story ones and right now the meter is at 70%, I finished yugutthian entity/viro weapons research but I have no idea how to progress the storyline/find a pandoran colony. I remember there being one on the map earlier and also a pandoran structure count but I can’t find them anymore.

You need to defend haven’s from attack! when you do this you’re able to locate the pandoran nest/lair/citadel where the attack originated from. Sometimes if you defend a haven really early on & ignore the colony that attacked it for too long, it’ll be abandoned to create a larger colony. So keep at defending haven’s and hope for the best!
