This still usable but me think with tribal village & watchtower mods can be clutter storm for watch towers.

Thanks!

Deleted my last message, figured it out. The problem was the icon to build roads was disappearing (but not camp building from Prehistoric Hunting - Better Camps).
Steel and Thunder Unique Units has a line that causes the problem but without destroying that large mod (I don't understand why the line is there in the first place), I found the answer in the Better Camps mod.
Add "OR REPLACE" into this line so it becomes "INSERT OR REPLACE INTO Route_ValidBuildUnits(RouteType, UnitType)" in betterrecon_road.sql.

Wow, nice work
