The easy way to report a bug:

• Verify nobody else had the same problem before creating a new topic.
• Find the most specific way to replicate the behavior you're seeing.
• Title the topic to be as specific as possible (think of it as the headline for an article you're writing).
• Include the steps to reproduce the bug in the Body of your post.
• Insert images or even video into the body if they are relevant to the behavior you are seeing.
• If this problem is specific to Android, PC, iOS, or genetically modified Cronenberg potato, please report it.
• Tag the bug with a priority according to how severe it is.
