If this is a Classic Garrys mod Collection, then the Classic Gmod Spawnmenu would need to be in here, right?

Well, I have been making one from a while ago, but It doesn't work and only some menus work on it, If anyone can fix it and upload it onto the workshop (don't care about credit) that'll be perfect.
