So, basically, tonight's (8/14) patch added a useless Trading Card Game window. UIs with customized UIAnimations files don't have the right definitions to support it, so they choke. Using my awe inspiring copy and paste skills, I patched together a fixed UIAnimations for Lodidodi. You can get it . Just unzip to your lodidodi UI folder and overwrite the file that's there, and you should be good to go. (After you reload your UI if you're already in game.)
Users of inferior UIs are on their own.
