I just got to the portion of 'The Corrupted Village' where I have been given the "Magical TNT" and am told to go to the nearby cave to blow up the spike. However when I try to go inside the cave, I get sent to the beginning of the cave with the message that would normally say if you attempt to go inside the cave before you start the quest. So somehow the game thinks I have not started the quest yet I have the final item needed to complete it. I cannot go backwards and get the three items used to create the TNT. Please help as I am stuck and cannot proceed!
