Had a 2nd story patio on my outpost and used raised ground to put a campfire in it. Thought I had it ventilated appropriately, went afk and came back to a smoke death.

Miscalculated swim distance once, and was clinging to a rock to regenerate stamina, then a wave crashed into me and knocked me just far enough that I ended up drowning.

Early on was running away from a troll across some stone. He smashed the destructible rock near me and I got stuck in the hole it created.

Decided to take the risk and explore the mountains without frost resist potions so I made an outpost and put several campfires nearby to keep myself from freezing. Unfortunately I didn't take into account the damage bonus those frost drakes would still have and got sniped through an open spot in the roof while I was managing inventory in the outpost.
