I am trying to assist my son with an issue he is having, so please forgive the fact that I don't play this game. We downloaded two new (to us) mods today--Lucky Block and Plants vs. Zombies. Neither is showing in the Mod List. I have tried removing all mods from the mods folder except one of the new ones, updating Forge to the newest version, and using both an unzipped and a zipped version of Lucky Block. Same problem. I added screenshots of the initial problem as well as the mods folder. Can send more if helpful. Does anyone have any other solutions? Thank you!
