this is a nearly useless bug report but i cannot do more, and nearly != entirely.
Debugger entered--Lisp error: (wrong-type-argument integer-or-marker-p nil) ... org-element--parse-to(6609 t (22642 63843 472865 490000)) ... org-element--cache-process-request([6783 6783 nil -174 (property-drawer (:begin 2759 :end 2804 :contents-begin 2772 :contents-end 2792 :post-blank 0 :post-affiliated 2759 :parent nil)) 1] nil nil (22642 63843 472865 490000) nil) ... org-element--cache-sync(#<buffer executive--a.org>) apply(org-element--cache-sync #<buffer executive--a.org>) ... timer-event-handler([t 0 0 600000 nil org-element--cache-sync (#<buffer executive--a.org>) idle 0]) when moving tasks with org-shiftmetaup. i have no indication that this is a new bug at all.
