Rank checking intervals
It looks like your system is ignoring one-time manual rank checks while calculating automatic rank check intervals. The next automatic rank check should always run after the configured time interval since the LAST check (whether it was manual or automatic), but not since the last automatic check. If the one-time rank check has been executed manually, the automatic rank check interval should be counted since the LAST check, which was in this case a manual check.

Thank you for your feedback. We plan to add an ability to set custom date and time for the automatic checks in the next version. If you want to change the time of automatic checks for your project right now - we can do that manually, just let us know.
