Thank you so much for answering. It's a little hard to describe, but my concept is something like the FFX Sphere Grid... sort of. It has different starting points, but once you pick, you are free to go anywhere you can reach from those start points. So some nodes may have multiple ways of being reached depending on where the player started. Anyway, this is very much a tiny hobby project of mine, and probably not worth a whole possible customization effort on your part, as I'm sure you are busy! I can see how trying to maintain your visibility system would be a real pain with a free-for-all grid. However, the offer is deeply appreciated!
