If i build a bridge or a tunnel when i have a demolished starting tile, while the end tile is not demolished, the whole tunnel price is less then i have a non demolished tile and a demolished endtile. See pictures

I have not looked at the bridge code, or tested if it happens there too, but Shorty reported that it affects bridges too, but not always. For more infos see http://www.tt-forums.net/viewtopic.php?t=24759&start=20

Caused by adding the price for demolishing the starting tile to the cost variable and then do bitshifting with it.
[code]
ret = DoCommand(start_tile, 0, 0, flags, CMD_LANDSCAPE_CLEAR);
if (CmdFailed(ret)) return ret;
cost = _price.build_tunnel + ret

///some lines underneath
cost += _price.build_tunnel;
cost += cost >> 3
[/code]
