Pathfinding disregards shroud

In the original series, if you ever command your units to go anywhere in an unrevealed map/terrain, the units would straight walk in (as if, shortest path, and nothing would be standing in their way). Only when new terrain is revealed and their path seems to be blocked the path finding kicks in (a new path is calculated to 'get around the obstacle'.

In short: Path finding assumes shrouded areas are always passable.

In openRA i noticed my units already took the best path possible, even though they had never seen the terrain. This kind of makes the path finding very smart, but I also consider this a bit of cheating.

Revealing shroud would really have an extra effect if you take the shrouded data into consideration when calculating the best path to reach a destination.

The issue does not name files, tests, or an entry point. Begin by locating OpenRA's pathfinding and shroud-handling code, then trace how a destination is evaluated when terrain is unrevealed. Done means units initially path through shrouded terrain as if it were passable and recalculate only when revealed terrain blocks that route.
