"Fixes" pAI being deaf. 

"Fixes" pAI being deaf. But this also makes pAI unable to see visible_message, audible_message and emotes unfortunately. I think it's better to have pAI able to hear sounds and what people say rather than emotes and other messages while we wait for a fix for the later. At least it will make pAI playable again.
