Per first post,
BSA Testing
The FCOM Team ask for your assistance with BSA testing for UFCOM, Oblivion WarCry and Bob's Armory Oblivion.
Required: You need to uninstall all resources from FCOM_Convergence, ...before using these bsa's. Do not uninstall Frans, OOO, MMM - only FCOM_Convergence, .... Use either BAIN or make an omod with just the meshes, textures, sounds from those mods, and install, overwrite and uninstall - then replace with bsa
So this bsa is overwriting what you otherwise have in the FCOM package as loose files. If you don't have the bsa, nothing is wrong. That said, the devs need to reupload that file now that megaupload is down permanently.
