Did you found an other mod to replace end-cake ?
I've got problem with my old modpack called "Growth" (https://minecraft.curseforge.com/projects/growth) . When people download this modpack , they get an error ("Cannot find child addon: 267030") from TwitchApp and the download crash.
I've send an email to TwitchApp support, i've send 2 private message to"darkValorous" and nobody answer me.
Could you please help my community and myself or tell me who to contact ?
