Curious: what version of thaumcraft did you plant them in? Also did they have pure nodes, and if so were the pure nodes in the trunk or branches. I ask because I was recently changing a desert biome into Magical forest for bees and general build purposes and I only experienced the change in a 15x15 area.
One of my silverwood trees has converted a 15x15 area. It has no node in it at all, which is confusing, as I thought only trees with nodes would convert the biome. I have another tree with no node that didn't convert. The other that didn't is a fairly small tree with no side branches, the one that did convert 15x15 does have branches. No idea if that is significant.
So, my observations so far are:
Small tree, no node, no conversion.
Large tree, no node, 15x15.
Large trees, with nodes, 17x17. Node types are unknown as trees have been cut down.[DOUBLEPOST=1392979798][/DOUBLEPOST]
I noticed DW20 updated in the launcher, anyone know when they will move 1.15/16 to recommended?
If problems are found, then never. If no major problems are found, usually a couple of days. In other words, as with all FTB releases, "it will be ready when it is ready".
