So I have tried to complete the new advancements, completing some of them worked fine (ex. hot tourist destination). But some other advancements did not work at all, the new advancement called "this boat has legs (see image)" didn't work att all. Also some old advancements that were just updated don't work either, the Monsters Hunted and Adventuring Time kept the mobs/biomes from before but don't update after killing/exploring a new biome/mob.
