I managed to find a Silverwood Sapling the other day and planted it on top of my house (which is pretty much just a hole in the ground). After several days, it finally grew into a tree and I noticed something odd. Originally, my local Aura was 468/468. However, when my tree grew, it dropped to 95/95. While the Flux dropped from High to None (and is now stabilized at Minimal), I find it odd that the maximum Aura dropped when a Silverwood Tree is supposed to spawn an Aura Node.
Is this a bug or is there some other explanation?
