For more information see here Bug Report Template Build:1.11.1 4453 Mode:single player SERVER NAME:- SEED-ID:- If applicable: MODIFIED PLAYFIELDS:- Reproducibility:always Severity:minor Type: npc pathing/collision Summary: Occlusion culling of devices may cause NPCs to clip into devices Description: The game may hide devices that aren't visible to the player. This may cause npcs to fall into said devices and be stuck in them when the player approaches. See the attached video. There have been reports of NPCs ending stuck in such devices even when they couldn't have fallen into them, but I haven't been able to reproduce that behavior yet. Might still be related, if there are other external forces than gravity that can also move npcs. Steps to Reproduce: 1) spawn the attached bp, set to zirax faction 2) move to the door so the npcs spawn. 3) move away until the game hides the furnace.
