(Nitpicking but...) Shrapnel do not and never have made or released patches for SEIV. Shrapnel sell the game. It's programmed and maintained by
Malfador Machinations
Anyway, yes, patches are still being released. Go to Malfador's website and there you'll find an email address for sugeestions like the one posted here.
I agree BTW - a little more control over how the AI uses mounts would give modders ad AI makers a lot more freedom.
