Saving data now, but occasional bugs need fixing

I've got the new feature working: the option to send your answers that make your fish to me so that I can then add it to the shared data pond.

Conceptually, I think of it as a 'Data Pond'. But in practice, it's the CSV file I use to store the data to build each fish from.

One of my testers found a bug in my code, which results in the fish not forming properly (some of the values remain undefined). So, I'm currently working on improving the code and adding more error catching.
