Polylines are non-coplanar

I've been getting this error on and off for about a year now, and I'm getting real sick of constantly erasing and re-drawing objects. So I'm wondering if anyone else has encountered this.

I sometimes will try to join two polylines (LWPOLYLINES) and it won't work. If I then try to fillet them with a radius of zero, I get the error that the two entities are non-coplanar. But they are. I've tried changing the elevation of both to something else (like 1) with no luck. I've tried the _FLATTEN express tool, with no luck. I've tried exploding, setting all the z-points to zero and then trying again, either by filleting with radius 0, or by converting them back to polylines and joining. Also no luck. I've tried purging (including purging DGN linetypes), auditing and even copying the objects into a new drawing.

 

The only thing I've been able to do that works is erase the object and re-draw it. For some reason, even if I put points at the ends of the line (or ends and middle for arcs), erase it then redraw using those points, it works. So the points are definitely coming in at z=0. I just can't figure out what's going on. One thing I've noticed is that this only ever seems to happen with drawings we get from outside our office. It never seems to happen on drawings made here.

 

Any help would be greatly appreciated.
