Sometimes when I mark a repeating task as DONE, beorg would put the log entry into a strange new drawer (drawer name seems to be random) instead of the LOGBOOK drawer.
Here is a video that shows the issue.
is anyone else getting this? you might need to check your org files as the issue is not the easiest to spot.
I have recently fixed a bug in beorg (although not yet released) regarding drawers being indented with spaces not properly parsed by beorg. Do you also use Emacs with logbook drawers which are indented?
