Game breaking karthus bug

When you pick the statue of karthus skin and do your dance the eagle sound effect regular sound effect going "waaaaaaaaaaaa" at the same time. 1 more thing are there any changes planned for karthus? Thank you have a nice day Edit there is another bug with karthus with his q but I am assuming you read reddit and have red this https://www.reddit.com/r/karthusmains/comments/58jrd9/karthus_bugs/ but just in case here you go :D
