This would be quite normal in a longish book with a Table of Contents,
requiring 3+ pages to show it all.

When you abort after an error, the job does not finish so much
of the information for the ToC is not written. 

Next run the ToC in the front-matter shorter, if any is there 
at all, but the preview is set to a physical page number rather
than to a logical one. Hence it can seem to be at a later
logical page.

Next run has all the ToC info, so the front-matter is longer
and the Preview jumps back to earlier pages, to compensate.

Any time you abort a typesetting run, you should expect to have
to typeset 2 or 3 times to get everything correct.

Is this explanation consistent with what you are seeing?

It would not be, if by "reTeX" you mean doing multiple runs
each time, (as with  simpdflatex)  before checking the Preview.
