1) You can give heroes a fixed name by giving them #nametype 29 or whatever, having declared a new nametype of that number containing only one name choice. How to do this is covered in the mod manual. Just search for nametype.

2) Really? I've never seen that. There's not much that can go wrong with flysprites either. My suggestion is to go to the missile weapon modding part of the mod manual and make sure you're using the right flysprite and animation length.
