Editing KML breaks icons

Question

Edit:

Solved it. When I was creating my new zip/kmz my code was creating various folders within the zip/kmz.

Changed: NewZip.write(addedfile)

to: NewZip.write(addedfile, newfl)

/Edit

I have KMZs that need changes to their points. The changes are simply updating their attributes - changing the values in the tables that appear when a point is clicked.

My method involves extracting the files from the KMZ to a temp location, making a copy of the "doc.kml", digging through the copied "doc.kml" for instances of text that needs to be changed, and then renaming the old KMZ, creating a new KMZ with the same name as the original, and adding the all the files (including my edited "doc.kml") to the new KMZ.

I have automated this process with a pthython script, but when I run it, any KMZs that gets updated have broken point icons. i can't find anything that would cause this - my changes are quite minimal and do not replace and obvious KML. Changes are formatted: "PR_A_1567_20" to "PR_AB_1567_20", so essentially I am adding an extra letter into a few lines of the KML.

Anyone know why this might break icons? Everything else still functions perfectly.

Thanks.
