They are, kinda, normal guards and everything are following the correct path, the player also has normal collision. We only experience this problem with the walker spawners. We did use a heightmap and tried rebuilding the collision.
Thanks for the advice @Hardcawcanary. I’m experiencing the same issue as the OP but unfortunately the steps you described didn’t fix it. Has anyone else had any luck with this? TIA
Recently the walkers have been beginning to behave more strangly, dissapearing body parts, doing crazy dances in the air etc. @Flak any chance these are known issues?
