This was not the original second season planned, the first scrapped season was a Minecraft one, scrapped due to scheduling issues, lack of footage and a base series all together. Terraria #1 was also scrapped, as many people died early. Both seasons were mentioned in Indago's scrapping Indacore Minez #1 video.
The original plan for Minez #2 was a sixteen person hardcore, because Indago accidentally invited so many people he wanted to get them in a hardcore. It was scrapped due to him being have to manage 5 timezones.
2 members would have been in this season but were replaced by Smash and Tepig. Quil and TheNintendoFox were planned along with Nooble but ultimately couldn't make it.
