I have a daily scheduled task with ... SCHEDULED: <2019-01-11 Fri 07:50 .+1d>
Recently, when I complete the task it not only moves the schedule to the next day ... but it also /_rewrites_/ all of the "Rescheduled from ..." entries in the LOGBOOK. For example, - Rescheduled from "[2019-01-11 Fri 07:50 .+1d]" on [2019-01-02 Wed 10:54] - Rescheduled from "[2019-01-11 Fri 07:50 .+1d]" on [2018-12-31 Mon 11:50] - Rescheduled from "[2019-01-11 Fri 07:50 .+1d]" on [2018-12-16 Sun 19:29] - Rescheduled from "[2019-01-11 Fri 07:50 .+1d]" on [2018-12-03 Mon 10:49] etc. Those previous LOGBOOK entries no longer are available; they are wiped out by new task completions.
