All,
I've found a bug that's keeping the fish from biting as they should. I use some special diagnostics to measure how much each fish is interested in a given lure at any given time, and I use that a lot to get a good measurement of how the system is working. It turns out those diagnostics were also fixing the problem. In other words, if I measure how well the fish will bite, they bite well. If I stop measuring, they stop biting. Now that I see what's going on I can fix it once and for all. I'll have an update today that will have the fish biting as they should.
