I'm having issues with the ponds too. I downloaded the patch the other day and bought CL on release. I do not use any mods/CC/cheats.
I created a pond, placed the sign in it, but when I visit the pond with my Sim, who has several fish in her inventory, if I click on the sign it doesn't give me an option to stock the pond. No option at all.
Can we only stock a pond if it is in our residential lot? Or in community lots too?
To clarify, I can add the "ornamental" fish (the ones found in BB with the ducks, insects, tadpoles, etc) but I want to add fish that can be fished.
Any ideas?
