My bot for the cave master challenge received the following html page (modified the values arguments). I figured this is a good a spot as any to report a bug. If there is a normal place to report bugs and I'm just too blind to notice it just let me know. I do not know the context of the action my bot was trying to take when the error occurred.
<html>
<body>
