I have a fairly small Franchise Zoo, but one that I spent days creating. The main feature right now is a Riverwalk, which is a continuous walking trail where the guests enter the habitats of the peacocks, flamingos, aardvarks, pangolins, okapi, springbok, gazelle & antelope. There is a continuous river that flows through every habitat. I have had this setup for a long time, at least 50 in-game years and it's worked well until today.
Today, I spent about 3 hours in Sandbox mode creating a building for my spiders. Then I came back into Franchise Mode and started placing the building, creating the paths etc. The building had a solar panel upstairs (with a hole in the roof for it to function). This is when the bug tsunami started. First, the mechanics refused to recognize the solar panel. So, I lowered it to ground level, still inside the building and still functional. Didn't help, they couldn't recognize it, so had to destroy it. As I'm dealing with this, I started to get tons of notifications about animals in the aforementioned Riverwalk that are "dying of thirst". what, they literally live on the river. I hustled over there & tried to get as many as I could into Quarantine, but I lost a few of my best Gold tier flamingos, and a couple of antelopes. I decided to address the antelope problem, since that enclosure was now empty, so I went to the trade center to see what I had, and would need to purchase either a male or female. I open my Trade Center...what! I have 72 animals in storage? This can't be right. I decide to filter by Thomson's Gazelle & get rid of some of those...try to sell the first one, and there's no sell option. Why? Because he's 0.0 years old. How in the world did that happen? So I filter my Trade Center by age and discover there are over 20 animals in there that are all 0.0 years old. This definitely wasn't something that I did. So I move all of the babies into their respective habitats to clear room in the Trade Center. I unpause the game to allow them time to get cleared out, then I start getting warnings for every single habitat along the Riverwalk saying that it's dirty. That can't be right, like I said, I've had this thing running smooth for at least 5 decades. The water suddenly looks brown. So, I use the water heat map, all looks fine, except the river is filthy. I click on the water pump that manages the river, and it says "bodies of water managed - 0". Hmm, maybe the water pump is bugged, so I'll plop down a new one. Same result...no water pumps recognize the river anymore. So, I'm frustrated and seemingly out of options. Running the game will eventually kill every animal in the Riverwalk. So, I click "Save & Quit" and CTD. Perfect.
