[Bug] Towns adopting players road even if disabled

[accord2]

I've set towns_adopt_player_roads to 0 but towns when growing keep adopting my roads.
In this save please check at Inácio Mestre Stream dock (2466,1242). This port roads were built by CMNL but they are being adopted by Inácio Mestre town.
I've also tested this at a new game and it also happened. In the new game when I used the Public player town growth tool the roads were immediatly adopted, but when I used the same tool on this save game that didn't happen. Nevertheless, normal growth (not tool induced) does adopt the player built roads.
