Ok guys, Thanks a lot. I appreciate all the advice y'all are giving me. I never knew about freezing layers before, and every time I'd go to change something, it'd change a crapload of other random stuff i didn't want it to. I scaled down an entire landmass thatway accidentally... lol.
I have a question regarding Madgardsomr's advice to scale down my forests, however. Is there an easy way to scale down every symbol I place for a given duration? I tried placing the forests and then scaling them all down at once, but that moves them and they end up on top of other stuff... I know there's an easy fix, but I don't know. it. Thanks in advance!
