I have 94/95 merlin trials done and I'm almost positive this is the last one. Problem is the ball gets highlighted but not the hole, and when I go to where I think you're supposed to activate the merlin trial it says I've already completed it. Now I have no idea if I have actually done it already or not bc I've been playing this same save for a year already. Did anyone else have this problem or am I going to the wrong place to activate the trial? Any help much appreciated.
