Dupes still "forget" to build metal tiles, must reload constantly

 I have this exact problem.  I will load my sav game and txt file,  any tile they are refusing to build, will say it is queued if I mouse over it or say its out of reach, when it clearly is not!   and as per the OP it is exactly the same if I exit and re enter they promptly go build it.  The tile in this case is near the far left and is on the start area line

Today I actually saw a dupe stop halfway through building the GP tile and go do build stone tiles of lower priority right next to it. She never went back to finish the tile and no one else built any.
