When I'm invisible and hidden, I'll take something from a container or lockpicking a safebox and certain NPCs will spot me. Take off the heavy armor and I'll be able to steal like normal but it is pretty inconvenient to have to do this each time you want to steal something just laying around or out and about, questing. Invisible should mean invisible! Even if you were to see your items getting lifted off the shelves and vanishing or hear the clanking of heavy armor, you can't see someone who is invisible. I know some guards use lanterns that can expose invisible players but random NPCs shouldn't spot you if they can't even see you. This is a very annoying problem. If this isn't intended, please fix this. Thank you!
