I think I finally find how to fix the bug with the already open chest in the treasures islands. I added another safety to make sure the chest is well set when you enter in treasure island. Or things, I add some secret chest in some leagues so if you walk over the terrain, you might see a question mark over your head. Press the input and if your are strong enough try theses challenges and win great price 🙂
Have fun! with the new build and tell me if you find any other bugs.
