I don't know... Probably not. There are alternate solutions though
A) if you want your unit to go to certain places (like in a circle or down a path) then simply use regions and order the unit to go from region to region.
B) if you want your unit to just run around randomly you can use the ability wander, or trigger the unit to move to a new location on the map every X seconds.
I've tried it out but to no avail.
Best way would be a big waypoint system, yet that would be quite hard with GUI access only. Unless of course you only have a certain number of units performing that stuff...
Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
