I can conform that these bugs happened before, twice, exactly the same scenes.
Bug 1 - "1 D" has disappeared suddenly, even though there are few hours remaining. But Booster remained active on next day and Timer resets at 0H:0M:0S to 23H:59M:59S. (Boosting active)
Bug 2 - At last few hours (5+) of Booster, Timer has stopped and changed into 'No Boosters Active'. As a result, ARP earned through Time on Site has not boosted. (Boosting lost)
