When there are multiple save files, if you click save without moving which file it highlights, it uses the last name on the list instead of the highlighted name.
So, for example, with highlight on file One,
> One <
Two
Three
Immediately click save, and it becomes,
> Three <
Two
Three
Yeah I confirm this. I have about ten "Toon Trails at Night 4", and most of them sre saves of ISDF missions. Somehow BZ2 knows the real names, because when I typed in the save game name (like ISDF 10.1), it will load the right file, but if you click on it, you have to clock on one of the "Toon Trails at Night 4" names
