My friend and I were just doing our thing at our base, suddenly 1 Rex, 2 Carnos and an Argy all just attacked my base from different directions.

What could we have done?

The only thing I can think of is, my friend and I killed a Pelagornis and stole its egg and a turtle egg that was near the nest.

It also seems to be reoccurring but not as horrible as the first time. Carnos will randomly run to our base when they were no where in sight. We are on Valguerro and our base is on a sand bar, so it’s fairly far from any spawns.
