I've been getting these weird error messages a lot. I'm going to link a photo to this post to show you what I mean. I think most people reading this have experienced this error too but it often comes up when I'm trying to update World at War, my MCW10EB add-on and the first mc pack ever created. If you know what's going on and how I can fix it then let me know. But if (like I suppose) It's a glitch then curse moderators, you need to fix this.
