Ah yes, the "wrap around" bug was what I'd read about here, long ago. Thanks for the info on how one might address it, Asai Nagamasa-san. I knew the that the Byz got some significant perks, but didn't know the specifics until now; thanks for that too. I've never taken the time to learn the TW file systems, so getting into any but the simplest of mods is not something I'll likely do. But it's good to know where to find the info if I decide I want to at some point.
