Tried to build spotlights on unfinished/finished houses. My engineer just can't reach the spots, one above the door of an unfinished longhouse, one on the corner of a finished stormhouse.
(Seems the build range has been reduced or something coz my guy has the same arms as before the patch..
Edit: got my guy to build SOME by manually telling him to go upstairs as he's too dumb to try by himself..
