Im on 5.2 still, I was having an issue where it would continuously reset the coordinator to Render0 instead of local host. Im building on a single machine. Deepseek is suggesting disabling the swarm agent completely and building eith just the lightmass.exe but im not sure how viable of a solution that actually is. If I can still build lights without the swarm and theres nothing but a build time increase as a penalty id be willing to do that. I tried switching all my lights to stationary and my directional and skylight to moveable and i get lights but no shadowing at all, static or dynamic
