hey guys I was wondering: how could my pool paths dissappear and I cant see them
if you can help I would love it

Are you sure the paths are still there? Are guests walking along the invisible paths or are there no paths at all for them to use?

A few of the earlier pool add-on custom sets created the problem of invisible pool paths. Have you installed any pool add-on CS?

If the scenery and rides are toggled off under View Controls it would make them disappear along with the pool and pretty much everything else.

Accidentally deleting the files for the paths might also do it. It is how some people eliminate the in-game coaster supports.
