This game is truly punishing at times.
I had just finished clearing out a far-away plains island with a fuling village, and started loading up my longboat to move on. The very last thing I did before I left was deconstruct my teleporter so I could move it to the next temporary outpost, and literally the moment I did I see "the ground is shaking". No big deal, I've dealt with two trolls solo before and I wanted to save my little forward outpost. I managed to get them both to down around half health, when all of the sudden two deathsquitos zoom over from far away, giving me the one-two death shot to the back.
Last time I tried to raft-of-shame my way back to this area (pre-teleporter), I got eaten by a sea serpent.
Odin's beard, I'm frustrated.
EDIT: This is almost too ridiculous to be real. After killing one sea serpent and dodging another, my server disconnects momentarily and I'm booted from the game. I get back in to see the karve zipping into the distance, full sail. I'm to far away to swim for it and die about halfway there.
