the interface for waterwheel disappeared. so after 2nd prestige i waited on it to finish building after the battle, there was upgrade buttons and my woods are about 31k, so i upgraded totem. click on the surface once and on waterwheel again but its just blank
To unlock the totems you need to capture the forest temple at the moment for the demo. That might be the reason why there was nothing yet. If you captured the forest temple already in that specific run and it didn't show up, then it must have been a bug and I need to fix that!
But maybe I should have let them unlocked once you captured the forest temple the first time tbh...
