How can I decrease saving time?

I’m using a demo map that I downloaded from the marketplace. It’s taking forever to save, even for minor changes. Saving things seperately doesn’t take that long, it’s only when I’m trying to (auto-)save my level map. It takes at least 30 minutes to save and its always stuck at 70 percent.

I already tried verifying; deleting intermediate, save and DDC folders. Nothing seems to work.

Here are the specs of the computer I’m using (I’m using an external ssd with 370GB free space):

  • AMD Ryzen Threadripper 3960X 24-Core Processor 3.79 GHz
  • 64.0 GB RAM

Buy internal m.2 ssd drive, for saving your project, or create game on small dev level that saves fast.
