Kentrosaurus Joins The Isle in Patch 0.21.720
The Evrima Public Branch update also tweaked weather, animation, AI, UI, and a long list of creature fixes.

The Isle’s Evrima Public Branch moved to 0.21.720, bringing Kentrosaurus into the game and pairing that addition with a broad pass over weather, animations, AI, UI, and creature behavior.
Official servers were taken down as the update went out, and players who do not see the download yet may need to restart their Steam client.
