Xbees not playing nice with eachother

Hey Paul.
By "sending debug data" you mean the Serial.print?
Am I wrong in assuming that "Serial.write" goes to Xbee and "Serial.print" goes to pc?
If this is so - in the specific cases where it goes wrong, I do not have any of this mix up.

Receiver - In this instance sends a confirmation:

case Play:
    //take care of variable speed
    stepper.setMaxSpeed(speedValue);
    stepper.moveTo(outPoint);
    stepper.run();
    //Serial.println ("Pcase");
    if(stepper.currentPosition()==outPoint)
    {
     Serial.write (1); 
     
     mode=Stop;
    }
    break;

Sender - In this loop waits for confirmation and needs to act

if (Serial.available())
  {
    dataReceive = Serial.read();
    if (dataReceive == 1)
    {
      pClickedOnce = false;
      digitalWrite(playLED, LOW);
    }  
  }
