I got 2 questions, first i once saw someone posted a console command to reset AI for some kajith or Argonian who was being aggresive, i dont remember the console command... if anyone know the command please let me know, second question is about making dragons appear by console, so far i am not following the main quest nor the story but i want random dragons encounters, can someone post this command too? thanks in advance.

select them, and use "TCAI", which stands for Toggle Combat Artificial Intelligence. problem solved
if you want to turn it on again, just repeat the command. easy as 3.14159...
the dragon command... "player.placeatme 000F80FD" will spawn a generic Blood Dragon (level 20). but it will spawn close to you. not sure how close, but very close. i reccomend having Become Ethereal selected incase it spawns close, and a powerful spell/scroll to charge while invulnerable

Ohh ok thanks ill try the command for the AI, about the dragons i was asking about the command to start making dragons appears randomly like in the main quest after the first whiterun quest.

not sure if it's possible to start the random spawns with console commands. i think you'll need to do the quest for that

Hmm i should had stored the commands in a txt file... i remember activating in the console random dragons for a save game i still use, so far i havent even entered to talk with whiterun jarl and ive killed like 9 dragons.
