Unloaded Bee Boxes do not produce Honey

Bee Boxes are supposed to produce 1 honey per day while they are unloaded. They have not been doing that in months, however.

After some testing with a lot of help from @Hornete, it appears the issue lies in the harvestable component's timer. 

The timer is supposed to countdown from 300 seconds during the day and add 1 honey when it reaches 0. 

But instead of simply stopping when dusk comes, the timer resets (I'm told it's got something to do with the Harvestable():StopGrowing() function).

So in the end, the bee boxes almost never fill up, except during summer, where days are long enough that the timer manages to hit 0 before dusk.
