so with the update that included this
"Paved tiles now decay by being overgrown with vines. If decay hits a paved tile, without an active claim, bordering a natural tile, or bordering another tile with vines already on it, vines may start growing over the hit tile. Further decay hits to tiles with vines will cause the vines to grow, until, finally, with the fourth hit, the paving, and the vines growing over it, are removed, decaying to a bordering natural tile. The effect in total being that paving decay of a large paved area starts around the edges and gradually corrodes its way into the center of the area. Suggested plenty, but among other places here."
Most large villages use different styles to create the look they want. They also employee different ways to protect the village and allow people to claim their own areas within such village walls.
In some set-up this would include a space between claimed areas that allow walkways The problem is that the decay factor is now removing such roads\pathways. Since there is no way to have claims border each other there is no way to prevent this.
Is there a way to tweak such decay? maybe allow decay not to factor in up to 5 spaces from edge of such active claims ..
