i use AI behavior toolkit ,and i placed 50 AIs in my scene, it works well.But if i place one more,there is one of those 51 AIs wont work,and i find the AI which doesnt work that it just run the move to task,but the character doesnt move.So there are only 50 AIs can work perfectly. Once i place over 50 AIs, others will dont work. Please forgive my poor English.
