What issue do you have?

Putting this in "Support" since there's not a "Bug/problem reports" section, and the section for feature requests doesn't seem quite on-topic.

I use bullet lists extensively in various types of notes, to arrange things like URLs to website resources in hierarchical fashion by site and section within site.

When I copy-paste a mis-placed list item to move it to where it belongs, frequently it appears mis-indented, and attempting to fix this very frequently silently deletes the list item immediately after the one I just pasted. I've never had this problem before in any other editor.

If you can't figure out what I mean, I suppose I can see about re-creating this problem on purpose and video-capturing it, though that would be a hassle. Really, just make a multi-level list and start copy-pasting items around in it and you'll run into both issues quickly enough.
