Landscape and water interaction

Hey all,

Trying to get some water working. It was working fine, and then something broke in an update I think, not exactly sure when it happened as I stopped working on the scene for a few months and when I came back it was broken. The water seems to be interacting with a collision on the landscape, or something similar. I am out of ideas how to fix this. I have 2 layers for the landscape, as well as the water layer. The water acts fine when I remove the landscape. I also tried some checks to make sure its not interacting with itself and breaking that way, and seems not to be that.

I am out of ideas, so any help is appreciated!

Thanks!
