Wanted to play Britannia the DLV way but with normal building times so I`ve changed the export_descr_buildings.txt myself. Tested and works well.
Just extract to
\SEGA\Medieval II Total War\mods\dlv_british_isles\data or
\SEGA\Medieval II Total War\mods\dlv_teutonic_knights\data folder and enjoy.
Construction costs are intact, DLV costs.
