Game breaking bug, freezes time and saving

I understand this, but its so weird because the last time I played which was around April, I had no problems with this, and I was on the same exact system.

I really only use prefabs so breaking up building tasks doesn’t seem to work for me.

Quick question, is this happening to you, since you know how to fix it?

This problem seems to have come up before here:

Looks like it was patched before…
