Hi all i have been having many warnings on Duplicate ID's past month and finally have time/energy to ask about this ;-) so each time i start emacs or switch org buffers i get a ton of warnings on Duplicate ID's: WARNING: 20 duplicate IDs found, check *Messages* buffer Duplicate ID "9276e354-d04c-43e4-a11e-27d90359b0a4", also in file /home/zeltak/org/files/archive/TODO.org_archive Duplicate ID "08e2584a-dc9f-49f9-b0b2-555d407a499b", also in file /home/zeltak/org/files/archive/TODO.org_archive Duplicate ID "da41e5f7-b9cf-4cd7-99e2-fad1f7844ab3", also in file /home/zeltak/org/files/archive/TODO.org_archive Made readonly!
