Twitter issue
Not sure how many people follow it, but FYI, I hope you're not too bothered by XanderCat being ommitted from the @roborumble Twitter feed for now. I'm pretty sure it's interpreting your bot name as a URL and failing somehow (they started auto-shortening all URLs recently). Even trying to post the same tweets through the web interface errors out for me. I reported the issue a week or two back but no response yet...
Although I'm not quite sure what you are talking about, as I don't use Twitter, I just tonight fixed the Download link for the JAR on the XanderCat wiki page. It has been broken for a number of weeks (I didn't realize it until today). I just mention it in case that might have had something to do with it. Or maybe that's completely unrelated. I don't know.
You know, I'm not sure how it works, but I use the NoScript add-on in Firefox and it currently blocks code from the Twitter domain twimg.com. Maybe that was causing the issue? I could unblock it.
