The latest bracket for the gathering log is 36-40 though. I took that to mean it wasn't going to show the new bracket until I gathered at least one thing from a 45 node, but I guess now maybe I should ask if I have to be 41, rather than 40, to see level 45 nodes. While I'd swear I've always moved up to the next level of node as soon as I hit x5/x0, I can't clearly remember doing that except with fishing (moving to the new zone, instead of node), so maybe I'm wrong.
