Same experience with the spiders. I had a camper outside the Oak Tree Lab.
I'm taking a break from the game after a swarm of Larva attacked my base.
I feel completely defeated after they ransacked all my supplies and tore down every wall. Even though I'm early on still, I felt like I wouldn't be penalized for putting effort into resource gathering and establishing a base; after this experience, I feel like there's no reason to base-building.
