The Rot plane spawned this reset, containing a mouldy favourite from last chapter.
Within it were Castle Creep, A mine-able purple crystal and Fungal Pygmie quests which all did not work because clicking on the bubbles/crystal did not open a dialogue.
We found a random in the same area. With a quest inside, that also has no dialogue if you click on the bubble.
Additionally, the transition towards the mushroom forest exists. But it cannot be traversed. Or perhaps that is because the lava bridge that is between the areas was not brought over to the module.

All should be resolved I think.
