I have been having the same problem for about a year now. I stopped playing my worlds, waiting for an update that will fix the problem. I went into a world that gets stuck on the save screen, to see if it's been fixed. I filled in my map, collected materials, and was able to save progress yesterday. But today, after building a pen to catch sheep, the save icon appeared at the corner of the screen and didn't disappear. When I saved and quit, it got stuck on the save screen again. I closed out the game, went back in and built a pen, and yep, it did it again. The save bug seems to be connected to building. We should have the option to turn off autosave and save it manually.
My games don't autosave, and when I try to save and quit, it gets stuck in the saving screen and never saves. It happens when I play with someone else. I made a new world, and played alone. At 90mbs, it started freezing up on the save screen. No progress saved after. I made a new world, it saved fine, until another player joined. Now it freezes up in save screen. World is at 60mbs and I can't make any more progress.
I've had this problem for almost a year and decided to play different games, hoping this bug would be fixed. Today, I tried again, but bug is still there. No progress. This issue has not been resolved.
