Good day, I am playing on Xbox Series X amd i have completed the below multiple times and still end up stuck each time.
It's morning of Fall Sun 28 at 7am. It's also the festival day. My crecreation center has been completed so as I approach the inner town I jump into the cutscene that opens the recreation center. When the cut scene finishes I go to exit the building and I appear to be floating above the center and am unable to get out of the area due to the festival. I have tried restarting the game many times. I don't want to miss the festival so I have not tried skipping the day yet to see if it works. Sadly I fear I may have to do that. I will update further but this issue was and is super frustrating.
