Lighting won't build on separate levels

Hello,

I am trying to build lighting with only certain levels visible. However, the lighting build always gets stuck if I don’t have my level “CBD_Bedroom” visible (see screenshot). Provided this level is visible, lighting builds fine.

The percentage it gets stuck at varies depending on how many levels I have visible. I tested by deleting assets from a level one by one to see if lighting would build, and with every asset I deleted the build got stuck sooner than the last time (e.g. get’s stuck at 93% with 10 assets, and 90% with 9 assets).

Not sure what’s going on here, thanks in advance!
