It doesn't save faster, it just completes most of the saving in the background. If you try to save while it's still getting saved in the background then you get the error popup.
I want to report that shift+left click is crashing my game in editor, already happend like 5 times, and isnt because im duplicating or deleting 50000 elements, are like 10 or so (last version on steam)(edited)
just corner from previous group selected color copy it and then in other group quads i was selecting all corners to put color (i did it and saw that one corner was not selected )but i didn't take left top so select + left top corner again and when i paste code it crashed(edited)

maybe it could be that my client was running 3 hours ?
It's seems like often happens like that when i run client to long .
