Buy an invisibility potion from Lucina. It might help...
i'll try it and let you know if it helps, although i think its a bug which might need to be looked into cause i didn't have a problem in it as much as i did in the newest version
edit: it actually worked, thank you so much for your help, i had tried move forward from that part so many times but gave up in frustration, the potion helped a lot so thanks again
