So I am unsure as to what to post, but here is my info;

I have a modpack in which I use
BetterEnd
EndRemastered
Oh the biomes you'll go
Repurposed structures
everything works as normal after defeating the ender dragon, thing is, when I go to the "other end" only the "Oh the biomes you'll go" works, none of the betterend biomes work

Should be fixed in latest release 1.6.1
