Probably jig up a workaround, but the destruction of a function makes me itchy.
I just tried reloading a single icon with readFile(url), and it works as expected. (which solves my original issue).
Collision somewhere in loadVars?

That ought to recreate the icon when the button is clicked - I imagine your code is using an existing icon before the interaction, right, and that icon is getting messed up with the first call.
