I'm still solving a few bugs from BAT 5.0, so I haven't released it yet. It will take approximately 2 to 3 months to finish, going by my current hectic schedule. It will be available at SourceForge like the other versions of BAT and the expansion packs.Where do I download those versions from? I see you have links in your signature, but they are only for BAT 4.1 and Better BAT AI 2.1.
Better BAT AI will take a bit longer, as the problems with it are quite significant, but the changes are worth the wait.
