Possible bug: failure to rout

[UP844]

For some reason, the units highlighted in red are not allowed to rout, even though the first hex of their rout path is not in the LOS of any enemy unit (this is also true for the path marked in yellow; the path marked in green would instead expose them to interdiction from a MG on a hill, not visible in the screenshot).

The units were not eve allowed to rout in Low Crawl mode, and so were eliminated for failure to rout.

There are no US units at all in the direction the of the route paths I have marked on the map.

Have I missed something or is this a bug?
