EDIT: This thread is a work in progress. Please contribute your two cents so we can figure this all out together.
I've noticed more and more people are having issues with mysterious problems popping up on their ponies recently. And I, for one, am totally confused by it all. I know there are others who are as well.
I have ponies with mold issues, ponies with cancer issues, and ponies with regrind issues. My idea here is to keep this post updated regularly with pictures and examples of all kinds of unstoppable pony problems. That way it is clear, and everyone can easily identify what their pony issue is and see what can (or can't) be done about it. I think it would also be good to list who is more prone to these types of issues, and what can be done to prevent the spread of these issues as well.
If you have clear pictures, or can explain these problems in a concise way, post them here and I will update this first post. Or, if you have questions yourself, post them, and maybe we can all help each other get them answered.
Here are some starter example pictures of a few ponies I have with issues. Please correct me if I'm wrong.
