No, you can’t turn off dinosaur aggression in the campaign, but you can reduce the risk.There’s no way to turn of dinosaur aggression in campaigns? Right now my rangers get attacked so often I’m tired of sending them in to refill feeders or medicate the dinosaurs and just let the dinosaurs starve to death or sicken to death! It’s so annoying - if the dinosaurs wanna attack then they probably don’t need that feed or medication all that much, and death comes to all sooner or later. I actually cheered when one dinosaur who kept attacking my ranger starved to death!
For example, you could place the feeders closer to the gate, so the rangers don’t have to travel far into the enclosure thus significantly reduce the risk of them being attacked.
Another option would be to send ACU to tranquillise the more dangerous dinosaurs, before sending your rangers to refill the feeder.
Or you could even do the tasks manually, personally I find this method to be the best one.
