I have tested all lots in Oasis Springs by dropping the same build with a fish pond. The trouble appears to be by neighborhood. When the fish were not jumping in the pond on the lot they were also not jumping in the community fishing holes in the neighborhood and vice versa. Neighborhoods with no fish jumping animation: Skyward Palms, Acquisition Butte, Parched Prospect.Forgotten Grotto. Neighborhoods with Fish Jump Animation: Bedrock Stright, Oasis Springs Commercial District, Desert Bloom Park.
All testing done in same game file using a vanilla game with all packs installed. Tested on MSI GS73VR 7RG. I know the debug pond on my lot (same build every time) is not compromised because fish jump animations all work in Willow Creek, Newcrest, Windenberg and Magnolia Promenade.
Red= No Fish Jumping Animation Green= Yes Fish Jumping Anination
I placed one instance of my build in Newcrest. I did not map out all of Newcrest. The thing to do would be to try each neighbohood and see if it’s. a Neighbourhood problem there also meaning if both on lot and off lot fishing spots have the same correlation between jumping fish working and not working. I will take that on and see if the animation presence or absence affects the entire neighbourhood im Newcrest as with Oasis Springs.
I have Sims living in Newcrest and their ponds have NO animated/jumping fish. So I don't know what you are testing to be hunest.
