Hi have a 166MB file (reflowable, all art), created w/Kindle Previewer (latest version, 2.51)

Spine lists xhtml docs in order of play; this matches ncx

Guide lists Start document, which matches first doc in spine.

On Fire and Mac app, mobi opens correctly
On iPad and on Touch, it opens to 4th xhtml in spine, not even mentioned in Guide
On K3 (updated), it opens to middle of 3rd document in spine: Table of contents, which is listed as such in Guide

Does anyone know why this is happening? Does the file size make the document go crazy? Thanks in advance.
