I made o Tech class enemy who gives shield to his allies.But a problem occur.I put it a A.I code to prevent him from giving the shield randomly but when ı do that my actors cannot perform any attack skill.İnterestingly they can perform heal or buff skills but they cannot attack to tech.This is only happening when the Tech alone.If there is an ally next to it, there will be no problems until that ally dies and then same problem occur again.I controlled everything one by one.When i delete the A.I Code there is no problem.But i when ı put the code that bug occures.Heres the enemy notes:
