Shaderforge: Tiled animated texture

Hi guys. I'm trying to create a simple shader where it's using an animated texture that repeats seamlessly. The effect I'm trying to create is caustics. I started with this node layout and that worked great. As soon as I try to scale(multiply the UV's with a value) the tiling it breaks. Does anybody know how to get it to tile correctly or can someone point me in any direction for a solution? Any help would be much appreciated. Shader and texture can be found here.
