Hmm, odd. It looks like a cache coherence issue. It could be a bug in
your version of FS2 software -- did you raise the issue with them?
Anyway, as a workaround try setting "coherent=on" (quoting from memory) in
fs2.ini (just an idea -- it may not work and you will lose some
performance though) or use hardware breakpoints.
