duplicate external linkages

[BelBearvan]

I have two projects linked through numerous external links, entirely going
from the first project to the second project and have discovered that MS
Project is providing duplicate (and at times triplicate) links of those
original links. When I attempt to delete the extra linkages from one of the
projects the program crashes or shows "create external" under tools-links
between projects-differences. When I delete them from the other project, it
shows the linkages deleted, but they always come back. Further, that "create
external" difference link cannot be deleted (the delete link button is
shaded).
Finally, one of the tasks in the first project is listed as "critical", with
the only successor being one of those duplicate external links, and when I
look at the second program the linked task is "not critical". As a result, I
have an extra critical path (with no constraints anywhere) that is nowhere
near the end of either project.
I've tried to write to .mpd and back, but it just stays. Tried moving to
other directories, deleting one or the other of the files and deleting links
before bringing back the deleted one. I am out of ideas, any help out there?

Hi,

You can only delete external links with both programs open simultaneously.
Moreover (I don't know whether this has been the case or not) "Save As" of
one of the files can modify addresses of the links.
