Seeing that Anna has her old steel walls (discounting the missing workbench) makes me think it's an older version of Anna in DF. That could be caused by not doing a fresh install, I know people are constantly saying that, but it is an issue. There is a way to fix your save, but first, back it up. Now. go into the game, turn on debug mode and find out which is chunk where anna is. Press f1, type dm, press f1 (to close the console) again, press f3, open the map (to get a mouse pointer) then toggle CH. Toggling CH will display what chunk you are inside (example Region: r.3.2). Go to your save game delete that region. It's in a directory called regions in the save/world area, I'm doing this from memory. Then go into your df mod folder, find the anna poi file, delete them and replace it with the files from the most recent version. When you enter the game Anna should be reset. Also, before doing any of that I again say back up your save.
