In the Werewolves pain card, there's a plus card for Pain Siphon. If you edit this card, it will also change the text in the non-plus card Pain Siphon and vice versa.
However there is also a Mind Meld card. I believe the person made it by including a +Mind Meld card in the Werewolves card and then clicking the resulting link to automatically produce a card. He put the data in. This also produced a non-plus card called Mind Meld with no content. The content between the plus card and non-plus card versions is not linked.
Why?
Wait, nevermind. Apparently I was annoyed by it making empty plus cards in the past and fixed the pain siphon one. You can delete this.
Your examples are always so awesome ;)
