This is a reasonable assumption given what I've described. It's been almost two years but from what I remember the problem was updating what should have been the same reactive binding in two different locations. When trying to debug a problem I was stepping through the code and noticed that the indicies passed to `$$invalidate` were different. Checked for typos and shadowed declarations and found none. Rolled back to checkout and found the indicies matched. In the process of undoing/redoing my conclusion was that the introduction of an unrelated reactive binding was the difference. I could have been wrong; I was pretty exhausted at that point.

Sure. In this case it was getting a big chunk of JSON back from an endpoint I didn't control and trying to use a number of reactive variables to select out pieces for display. I've done similar things in a half dozen other reactive/FRP libraries without issue but I assumed I was off the beaten path in Svelte.

I realize that this is empty complaining about other peoples' hard work. I don't have the code any more and I don't have a reproducible test case so I have no problem with anybody waving this off.
