In this episode of Hermitcraft Season 7, Mumbo decides the mycillium resistance isn't for him, and switches sides. A lover of Minecraft piston vaults, Mumbo couldn't deal with the low quality vaults in the Mycillium resistance HQ, and also the sever mistreatment of vaults by members of the Hermitcraft resistance. Mumbo also does some work on the Mumbo mega base, adding new elements to the huge automatic item sorting system.
