Uh, thanks, probably I had just ovelooked it, since it wasn't my case

Yes, it seems to be a problem with models or textures; I don't think it would be dangerous to change them, but making a backup is always good... I think I'll go on with the current model until I get a CTD or something (but in that case I think I'll dismiss all equites praetoriani and just use TWFanatic original version of the minimod; I'm Romani after all)
