Thanks for the many replies. A quick update/summary: I know my first career had all the required updates before installing OM. The only "mod" I may have installed was a hack I made to increase the number of officers/petty officers, but again it wasn't until 01/45 that the saves died. My re-install after that, I can't guarantee I brought everything up to 1.5. Again, I had multish4 installed (for the first time) and may have botched the install. I have now blown everything out, re-installed (just one sh4), updated, started again, so far so good. A new question: Is each save a complete set of data, or does it build on prior saves (only capturing changes)? If I had say, 10 current saves and I wanted to reduce the number, could I safely delete the oldest 5 from the current patrol?
