Achievement "Adventuring Time" doesn't work.
I visited all biomes including the variants and the achievement was not unlocked.
I suspect it is because the biomes 10 "Frozen Ocean" and 20 "Extreme Hills Edge" don't generate in this snapshot.
Steps to Reproduce:
1. Visit all biomes and variants (there are two different "Mega Spruce Taiga"
2. You will not get the achievement
Edit: It only works if the ONLY biomes visited are the existing non-variant biomes except Nether and End.
