AutoCAD Inventor :: IDW To DWG Shifting Text

I'm using 2013 with all the latest updates. This is what we're seeing, on exporting drawings to dwg, nearly all title block text is shifted from it's constrained position.

Case in point. There are like 10 lines for customer information. One line will look like the following:

JOBSITE: MIAMI, FL

In that example, JOBSITE is a single text object with bottom left justification. MIAMI, FL is a single text object as well that is a linked custom field with bottom left justification.

Both of these are constrained to construction lines in the title block. I've locked the text's insertion point to the intersection of lines, and to a point. In inventor, it works great. In editing the title block these things do not budge at all. They're locked up tight.

Problem is when exporting to autocad, the JOBSITE text will shift down and the MIAMI, FL text will shift up.

I thought maybe the constraints were off, but not that I can see. I removed all constraints and floated them and the same thing happened. Seems to happen no matter what we do. I turned the construction lines visible to see if they had issues and they hold their place fine. The text still shifts. The only text that seems to hold its spot are the pieces of text that are top middle justified.

There is ONE WAY to get the text to hold it's place. Export the file to a 2013 Inventor DWG file. That holds the text in the correct place. However, we need these files in normal 2010 format for a client. Saving these from autocad 2013 to 2010 works fine. However, it's more than 2x the work.

I've seen a couple old posts talking about multiple text types/sizes in one object but this isn't the case, every bit of text in the title block is a separate entity and a singular height and style.

And on a related issue, it's be nice if Inventor knew that things like commas and slashes and whatnot are permitted to go below the bottom justification lines and not force all the text up but that's a separate issue.
