Hi
I have some problems with my childs. I start a game with choosing the option that "I have family", and the children do not load textures. I try:

• Start a new game
• Disable all mods and just loading the MCA and RedCore.
• Check the google for solution of this error.
• Reinstall my Minecraft (clean installation)
• Change the Launcher (Tlaucher to ShiginimaSE) with the Reinstall of Minecraft (clean installation)
• Downgrade my Minecraft and try the MCA for 1.12 and RC too on Minecraft 1.12 version (dont 1. or 2).
