I’m seeing two things happen in a number of larger, more complicated spaces.
On re-opening a space, connections are drawn offset. Sometimes just by a few pixels, as shown here. Other times, they’ll be way off on the x or y axis. I don’t have a screengrab for a big difference, but this here is common.
Random notes will drop their final character. The note below read “Valley Falls” two days ago. And you can see an obvious truncation above, called out with an arrow.
The offset connections can be fixed by selecting all and nudging all notes with the mouse. I’m seeing it pretty often, though.
