Adventuring Time advancement still accepts non generating biomes

The Bug

Despite biomes like edge & hill biomes no longer generating they are still accepted towards the adventuring time advancement

Reproduce

• Make a single biome with a biome that doesn't generate anymore (like Giant Tree Taiga Hills)
• Kill a monster to activate the advancement screen
• Go down to adventuring time
  Notice that despite it no longer naturally generating it still counts towards the advancement

Expected Result

The non generating biomes no longer count towards Adventuring Time
