Lighting build progression stopped at 99.97% in importing results

Hi everyone,

I’m building lighting which started at 12:15, in the Swarm Agent log, then at 12:22 it stated Lighting 100.0%.

Now, at 13:51 it’s at 99% (Screen cap 1) or at 99.97% in the Swarm Agent, which is in Importing Results (Screen cap 2).

What’s going wrong here and most importantly, what can I do to resolve this, or speed this up? On this attempt I’m only using my local machine on the swarm. Lighting quality is set on preview.

Thanks in advance,

This occurs when building the light for a persistent level.
