Overview
Mistlands_Lighthouse1_new is a Valheim world location that spawns in the mistlands biome, identified internally as Mistlands_Lighthouse1_new. World generation places up to 100 per world, with terrain constraints (max delta 40, altitude 1-20), and an exclusion radius of 20m, which is why some seeds have far more of them than others. The data tags it as slope rotation and randomly damaged.
