Guardian Farm

Guardian farm problem that started in the previous update before the BTU moved my ocean monument 15 blocks away from its original location I built a farm around messing up the entire farm. This was not fixed not with the BTU update I convert my server the guardians don't spawn anywhere around. I made an ocean explore map to find the nearest one to replace the one I had previously built the farm around. After flying on creative for 25 minutes I finally reached it...... 25 minutes away FLYING from my main base....
