Hi cosmogonies,
We’re seeing the exact same problem, except it’s a much much longer delay this is probably proportional to the number of actors loading. For example, our World Composition PIE loading time was between anywhere between 5 and 20 seconds, and now it’s something like over 3 minutes.
Travelling from another world can take upwards of 10 minutes in editor for no apparent reason, when it used to take 30 seconds or so in editor.
The engine appears to utilize all available RAM too (in my case 64GB).
