Patch 1.0.16 for Valheim appeared in the game's Steam announcements on Sep 25, 2026, with a fix for terrain modifications that reverted in Deep North after the area was unloaded in some cases. The notes also listed fixes for a bug that could cause too many enemies to spawn, especially during raids, and for achievements that did not unlock correctly. The post said the patch would need a few days to reach all platforms, and that crossplay would keep working in the meantime.
