Construction units on patrol fail to move to repair a nearby unit that's just outside their build radius

[springraaar]

happens on any recent builds, 2438 to 2583 MF v2.41c (or any version) Any map

• happens when damaged unit is moving outside the builders build radius
• happens despite disabling luaui and luarules
• sometimes when the damaged unit stops the builders move to repair it properly
• holding shift while the builders are selected shows them repeatedly issuing the repair orders over the patrol but cancelling them immediately after
• maneuver or roam move state doesn't seem to affect it

^--- actually a .sdfz replay file

i disabled luarules and luaui, added 3 construction vehicles and set them on small patrols, added a nearby tank and ran it over a mine then drove around a bit. Some of the construction units move to repair it but their behavior breaks and they often fail to move to meet it throughout the next minute or so, then at about 1:30 i stop the tank and only then the two nearby builders move in to repair it.
