Hey Leslie, I have a couple questions for you: I purchased the older Map Nav (Version 1 I guess) this past summer and it's been fantastic! But now suddenly, nodeLinks is consistently returning null on a node that very clearly has 4 connected nodes. Have you run into or heard or anything like this? Any idea what causes it or how to fix it? And does version 2 have a Line of Sight system (where units' vision is blocked by walls, higher elevation nodes, etc)?
