When the bug happened, the champion would move to their new position with the move block, and then fire off the cone spell ability backwards, in the direction from which they came. Their respective kits practically depend on this combo. Performing a move block spell into a cone spell was key, which explained why Kassadin and Nidalee were experiencing the defect much more than other champions.

We narrowed in on the problem having to do with using certain abilities in a specific order. While Production and Insights pulled the winrate numbers for the affected champions to figure out impact, the rest of us started working on reproducing the issue. Our Network Operations Center technicians jumped on these reports and started paging out to the people on-call right away. This meant they were losing clutch fights. Players said they weren’t doing damage when expected, or they were performing abilities in weird directions. Messages began to pop up on the boards and social media about Kassadin and Nidalee in particular not behaving properly.
League of legends download not found Patch#
The first full week that patch 4.18 was live, we started to see the first reports of things being, well… a little wonky for a couple of champions. We had put a lot of work into these patches to prepare for Worlds and for a chunk of the dev team being gone, so the expectation was that it would be a relatively quiet week. I volunteered to stay behind and be the QA Lead for the Worlds patches with a small crew so that we could jump on any problems that might arise ASAP. Worlds 2014 Grand Finals in Seoul, South Korea. This way they could get a firsthand account of what players want, need, and get the most excited about. That year, the World Championship grand finals were held in Seoul, South Korea, and a number of folks from the League dev team went there to experience it and to really interact with our playerbase in person. The patch we’ll be talking about, the 4.18 patch, was what was live for our players for Worlds 2014. Usually, this means the tournament is a patch or two behind what’s on live. There’s the patch the pros play on during the tournament, which gets locked down earlier to ensure extra stability, and then the patch for the general playerbase, with more recent changes and content. Generally speaking, during a League of Legends World Championship, we actually have at least two patches to maintain. This is the Bug Blog for League of Legends patch 4.18, aka the Worlds 2014 patch. We learned a lot from this experience, and I hope that you can, too. So, for our very first post, let’s take a look at the one-two mega-punch that happened at one of the worst times possible.

And, I mean, c’mon, who doesn’t like to cringelaugh along with a really good bug story? I know I sure do. We hope that by sharing these stories, we can help others facing similar struggles to totally avoid making the same mistakes that we did, or provide some ideas for solutions when things have gone sideways. Our Bug Blogs will cover especially impactful bugs, ones that were difficult to triage and solve, and the ones from which we learned and grew the most. Don’t worry, though, we’ll cover the nitty-gritty technical details, too.
League of legends download not found code#
After all, in my experience, the true root cause of a defect oftentimes isn’t necessarily in the code or scripts itself, but somewhere in our tools or processes. With this in mind, we want to share some of our more interesting bug challenges so that others can see how we work through them, both in the short-term and in the long-term. That’s how we grow and that’s how we get better. And that’s okay! What’s important is to recognize failures for what they are, work to understand why they happened, learn from them, and make needed changes based on those learnings. We make mistakes because we’re humans, and humans are far from perfect. So, why do Bug Blogs? Well, at Riot, we believe that a fundamental component of the development process is understanding that failures can and do happen. I’ve been working on League of Legends for quite a while now (seven years, to be exact), and let me tell you: I’ve seen some… stuff. Hey folks! I’m Jane “Wilwariniel” Jeffers, QA Architect on League of Legends, and we interrupt your regularly scheduled Tech Blog to bring you the first installment of the Rito Bug Blog Series!
