Thanks for sharing… I see the problem, still working on a fix.
The problem is that in your file you have many non-project items at top level (0 tab indentation) indentation mixed in with your top level projects. I think you wouldn’t see problem if all your top level items were projects. With that said TaskPaper “should” be able to handle your case, and I would have thought it already did, but apparently it doesn’t… I’ll try to get a fix out soon.
For example this should reproduce the problem:
a:
b
c:
And then try to drag a:
to after c:
and you will see that it instead gets inserted before c:
. Anyway thanks for the report and I’ve deleted your file.
