nudge problem

hi, i'm having a problem where hitting numpad keys to move a destructable around, even holding control, and with nothing near, won't move it. it is happening with, for example, a log bridge, and some stairs. what could be causing this? I can't find any fields about it in the object editor. selecting nudge in the edit menu also don't move it, but it's not greyed out there.

EDIT giving them circle of power pathing instead of none seems to fix it.

That's because it works fine both ways, only when pathing is set to none, the units of movement are so rediculusly small, it moves within the same grid as normal units, which you know is a damn fine grid, because it is not even noticable.

nope, i tried holding it down for a while, no effect. with no pathing doodads, moving them is a little at a time but totally visible.

is your numlock on?
