How can I fix a stitching error in AutoPano when adding another image breaks part of the panorama?

I have a panorama that stitches correctly in AutoPano when I use only the four left-most images. But when I add one more image on the right, a person on the far left is suddenly stitched incorrectly.
I’ve tried stitching the panorama in smaller parts first and then combining those results, but AutoPano applies color correction and other adjustments separately to each partial stitch, which makes the final merge inconsistent.
Is there a way to manually guide the stitcher so a specific area comes from one source image, or otherwise prevent that local stitching error when expanding the panorama?

I do not know Autopano --- but Hugin has masks to correct this problems. Hugin is not the most user friendly app, but it's really powerful and has a lot of advanced options for stiching. And it's open source, and free.
In your case, the trick is to use masks to tell the program that one part of the panorama has to come form just one image. There is a nice tutorial here: http://hugin.sourceforge.net/tutorials/Blend-masks/en.shtml

Yes — the usual fix for this kind of local panorama error is to manually guide the stitch by masking or restricting which source image is used for the problem area.
Several stitchers support this directly. For example, Hugin lets you use blend masks so you can tell the software that a certain region should come from one image and not another. That’s a common way to fix people or objects that get misaligned when the panorama grows.
If AutoPano offers masking or manual source selection, that’s the feature to use.
If it doesn’t, a workaround is to export the correctly stitched partial panorama at the highest possible quality — ideally as a 16-bit TIFF — and then stitch the remaining image(s) onto that exported result. This may slightly reduce quality, but done in a high-bit-depth format the loss should be small.
So: first look for masking/manual blending controls; if unavailable, use a high-quality intermediate export and continue stitching from there.
