My project suddenly started giving the ‘Swarm Failed to Kick off’ error that seems fairly common but not very specific.
The project is in 4.19, and worked fine up until today. I haven’t really changed anything (added a few lights which I deleted).
I have tried building other levels/projects and get the same error if they are in 4.19 but not in 4.18 (so it doesn’t seem to be anything project specific).
I first tried clearing caches and then removed and reinstalled UE 4.19 but nothing seems to work. It’s frustrating because it’s an archviz project that requires regular updates with the client and saying ‘the software I’m using is giving me a mysterious seemingly unsolvable error’ doesn’t look to great and delays the whole process.
Any ideas?
