Simple Brain Mod (?)

[Auklin]

I'm trying to make it so Maxwell's lumber minions only target fully grown tree's (server side mod).

I was hoping to find a list of choppable objects in the shadowwaxwellbrain but instead found a more complicated check system. 'm not familiar enough with the code and was hoping someone could give a run down. I have a feeling I will need to add a new variable to all the tree objects, unless there is a way to check if it's at it's maximum growth cycle.

Thanks
