i had the same issue but mine happen when you get to the saving point and you climb the plattaform full of storm troopers after you defeat them all a space ship should appear and cut the wire that holds the plattaform but at this point im stuck the ship never appear and i cant go back because the ship suppose to cut the wires Cal should fall down and you should get a cutscene at that point but im not getting anything , and i dont want to start the game all over again if i have to do this i preffer to sell the crap of it
