I can't activate the sigil stone in the Skingrad oblivion gate. I believe it is oblivion world 4. I've scoured the internet for a solution to this problem. I'm on the xbox so console commands are not an option. What should I do? I'm going for a 100% playthrough and I'm screwed if I can't close all oblivion gates with world 4. JSUK: The option to activate sigil stone doesn't even appear in the bottom of the screen. The stone is like a piece of scenery. I have a save before entering the oblivion gate. I have reloaded and retryed multiple times. Help me great forumites!
