1) Finding AISettings.json

Inside your server profile go inside ExpansionMod/Settings/AISettings.json (the server profile is where you will find the crash logs, script logs, rpt, permissionframework, expansionmod, console.log and many other folders related to mods. This folder sadly can be renamed and can be found under many names like "config", "instance", "profile" or "sc" to only name a few)

2) Setting yourself Admin

Inside this file you will see a setting similar to this:

"Admins":[]

You will need to give your SteamID64 to make yourself admin

"Admins":["76561198959715227"]

You can also make your friends admin as shown with this example:

"Admins":["76561198959715227","76561198144647312","76561198045934831","76561197968396131","76561198103677868"]

3) Using the Debug Menu

You will be able to spawn allied AI following you, make them change formation, tell them to follow you or spawn hostiles AI
