It may have to do with how high the terrain is above the water table. Try making a bond in Bluewater Village if you have OFB, or one of the other neighborhoods and see if it works.
Yes. The problem I had, appeared when I tried to refill a pond. I thought that tool will allow me to do that. But not.
Now, when I need to refill a pond, first I delete it and, after I set the level of the terrain I want, with the proper terrain tool, I use the water tool to create the pond. And it works fine. :angel:
Thank you Ancienthigway.
