Hey nikyofficial,
You can use AimAssist and TriggerBot at the same time, that should not be a problem. Make sure you're on the latest version of Wurst if they seem to be disabling each other (I think there was a bug in an old version where that happened).
You just can't use AimAssist + Killaura or similar combos, because then you would have two hacks trying to aim in different directions at the same time and fighting over where your aim will go.
Hope this helps!
