Nice - I realized before replying that this could be useful in #wiki so I updated About The LifeMap
Nodes play absolutely no role whatsoever in the LifeMap display. They’re only referenced via NodeHunter, which is a decently simple query of “give me the unfinished Nodes for unfinished streets in the current browser view.”
Ooh, also, I took a step back to think of any possible way that there could be something wrong with map creation (the actual building/serving of the advanced LifeMap is one of the most reliable pieces of the site so far). There was a bug with the plugin I use to generate encoded polylines a couple days ago, and it looks like that did affect 11 of your activities - so that’s what was causing the LifeMap to fail to build. I’ve queued up your account again, so that should work properly this time - looks like there’s a ~40min delay in there.
