belt should be blue or purple. , work if i deconstruct them

I have the same issue but i found a easy workaround:

Go to Mapview and mark everything of your base for deconstruction. Immediately press ctrl+z to undo.
Map will be rendered with the mod now. But it would be good if the mod checks if it is used in a existing savegame for the first time to rerender the map without using a deconstruction workaroud, because you may mess up with that method.

there's supposed to be a check in the mod that does it automatically

"supposed" =)

@frinx, if i use deconstruct planner, i have 90% chance to remove all belt and move MANY ressources to logistic chest, not optimal
