    [BUG] HELP! Swarm Agent Fail After Latest Build

    Since the latest build, one of maps has a swarm agent fail, I've tried various things, like deleting meshes textures and so on, but I'm still getting a fail All other maps build just fine. I haven't added anything new to my map since the new update, and it build just fine before then. Any ideas?

    Swarm agent log.

      Try deleting the cashe and making sure you're only running one instance of UE4.

            Clear the cache here



            As mentioned, make sure there aren't multiple instances of UE4 or the Swarm related processes running (use the task manager).

                Did you make sure to update the swarm coordinator and other swarm agent applications? Sometimes new engine versions also include new swarm agent versions.

                    This is odd. So I just looked it up.

                    Old version of Swarm Agent: 1.7.2893.0
                    5/12 version of Swarm Agent: 1.7.2892.0

                    It looks like it was reverted?

                      I just fixed mine by copying all the files in C:\UnrealTournament\UnrealTournamentEditor\Engine\Binaries\DotNET on my Editor computer to the folder in my Swarm coordinator computer and used them to start it. Weird because now it says both are using 1.7.2893.0

                      Edit: actually I am an idiot and was looking at the swarm agent on my laptop, not my desktop.

                              OK, after hours of trial and error, I found that if I remove all the DM-Chill ice assets the lighting builds. Not sure why they no longer work. So fingers crossed it doesn't mess up again! If it does I will let you know.

                              BIG thanks for all the help everyone! it's very very much appreciated!
