I am currently on Chapter 9, trout of this world. I spent my stars on new trees and plants, but now the game won't progress. They both say complete, but it has not given me anything else! I even changed the trees and plants I chose in case that would trigger the event, but nothing happened (other than the change). The levels all run fine, so I'm accumulating stars. This problem has been happening for about a day now. I am using a Google Pixel 3a.
