Bug ( Game Crashes) During Treasure Hunt Event

My game keeps crashing when I click on the last expedition site during the treasure hunt event. This site had a pink check mark when the treasure hunt event first populated - maybe from a previous event - but I thought it might allow me to access the site once I unlocked the last site but it still crashes my game when I click on the site even after unlocking it.

I think the game has detected it might be a bug from it crashing and me opening it back up multiple times since it gave me a pop up that said it is detecting the app might have a bug and wanted me to clear my cache to see if it fixes it but after I cleared my cache it didn't fix the bug.

Any help would be appreciated.
