Thanks for the information . There is a small contradiction in your answers though (yes, I've played too much Phoenix Wright ).

You say you've applied the permanent fixes, yet you say you tried the typo fix as temporary. That one is a permanent fix... Are you sure you've tried all the temporary fixes, in combination?

Anyway, I think crashing due to naval battles is a first, and unlikely to be covered by the fixes really. I'll be taking a look at it sometime unless someone beats me to it.
