I've recently bought the deluxe edition with wild and soaked, but i can't make the pool or path around it flush with the surface, they just cause the ground around the pool to dip. The first pool I made did it its self properly, but now all the rest of the pools just cause the ground to dip. Can anyone tell me how to fix this?

Are you familiar with how to raise and lower scenery, i.e., are you using the shift key to lower the pool position while trying to build/place it?

I know some of the in-game tracks cause the ground to dip or rise when attempting to place them anywhere but level. I'm not familiar with the deluxe edition but if the edition you have comes with pools ready-made they might be set, just as some of the in-game rides are, to adjust the ground up or down by default during construction/placement. Try building a few tiles of a brand new pool you create yourself to see if this still happens, or try placing CS pools that you know didn't come with the game which you know for sure haven't been made over from in-game pools into CS.

Thanks, all I had to do was hold the shift key.
