AI phyics movement doesnt work

I am trying to make an AI who picks up blocks and brings them to appropriate container. For some reason my AI stops at random times sometimes he picks like 4 or 5 blocks and brings them to the container sometimes he managed to get 16 blocks in container. Can somebody check my script because i dont know why my AI just stops random at the times and doesnt want to pick up blocks. I tried to put Debug log in my if statemates to see if it goes in and it does. My AI goes in the if statemant but he still doesnt move.

    }

    if (target.CompareTag("RedPosuda"))

        transform.eulerAngles = new Vector2(0, 0);
    }

}

}

I found whats wrong. For some reason my targets position in debug log is 5.3 but in my unity scene my targets position is 10. Every time it happens in random position in random time. Please can somebody explain to me what is happening and how to fix it?
