Fully grown arbor tree branches no longer creating Harvest errands

1. Grow an arbor tree branch

2. Save the game right when the arbor tree branch finishes growing but before the "Ready to Harvest" status appears

3. Reload the game, and note that the branch is no longer harvestable

There are definitely interesting circumstances that makes this tree farm different from others. They're exuberant,  they're planted on top of ethanol distillers, and this is on an extremely large and laggy save. However, I was able to reproduce this issue even without stacking buildings on the plant. The exuberant makes it happen much more frequently as each branch grows in 1.125 cycles rather than 4.5. Pips eating the branch does not fix the status. Pruning the branch and letting it regrow does, although this is difficult to do in my situation.
