Hiya. Upon testing, psy deaf pawns seem unable to see invisible pawns same as everyone else. I'm going to change the page now but I wanted to reach out to ask why you thought that wasn't the case, just in case there was something I missed. I know the description implies thats how it should work, but it doesn't appear to be that way in actual gameplay.
Hope this isn't discouraging, your edits have been good and mistakes (assuming I'm not the one missing something) happen.
