I had seen them around and always been careful around them before (pretty hard to miss and easy to avoid), but my first actual fight with one actually happened inside the base of a tribe I just joined. It spawned INSIDE THE BASE.

I let it chase me into a room and locked the door behind me, only to realise that it was the same room as the tribe fabricator.

It set a bad first impression on the tribe leader and I got kicked out later on for other reasons, but yeah. Don't build your base too big or these guys could spawn in while you're at the smithy and wreck everything inside.
