Trees stop growing after changing the number of saplings to spawn

[Shark]

As the title says, info6.txt has a property called `MaxNumTreesCanProduce` which defaults to 2. When that number is changed to 5 or 20 (or even reset back to 2) the trees do spawn more saplings when watered but watering trees themselves is broken so the trees don't grow at all. Same applies to little saplings too - they also spawn more saplings but just don't grow.

This makes for a rather unpleasant usage of "use mod, spawn a quick forest from a tree, save, quit game, revert mod, turn teh game back on and keep watering trees" usecase.

How do i keep this increased saplings count AND not break watering mechanic?
