Blocking 127.0.0.1 due to a 'server full' attack (1)
That means there is too many bots connecting at one time. Its something new with 3x that is built into the server to help prevent bot attacks. Just connect your npc's with a delay each time or connect a group of npc's, say 10 npc's per 5 seconds, and they should all connect.
