I did, after a clean installation of the game following on the steps that are specified at the frequently asked questions about 7h, the first thing I did was try the mod with Mike+Millenia option and the sword was still broken I no longer know what to do except chose another option and wait and hope until the catalog gets officially updated and that this mod gets a fix that way...
Another thing that happens is that the buster sword instead of using Mike's Buster Sword it uses Millenia's instead for the textures when I activate the option of mixing both so I think it's a problem on how the mods where put in that combined pack for that option. I would love to install them manually, but it requires opening a file I don't know how to open and I don't wanna dive there in case I break anything
Um, just opening .iro files is an option right in the top tab, click Workshop, select IRO creation tool. Next, click the Unpack IRO tab. Then make a folder, copy the folder location and paste the location in, Output Folder. Finally, select the Source IRO and find where your .iro mods are, generally in your FINAL FANTASY VII\mods\7th Heaven folder..
Look at what comes out and see if something's broken that way, because I have zero issues with any battle mods UNLESS I use other mods at all.
However, with multiple uninstalls and re-installs it's possible some of your IRO files got messed up. See, I have to completely uninstall the iro's and re-download them, too I can't use 7th Heaven backups, I never run without fresh ones, in a separate, clean backup folder, if any at all, AFTER uninstalling them from 7th Heaven, and I tear my IRO's apart to check if things are in the right places..
