I have been building a large board in Trello with extensive use of internal links between cards. I used the #[card number] format for my links, which worked very well. Now the # links no longer work. I can't find any reference to this on the Trello help site. I'm using Chrome Version 47.0.2526.106 (64-bit) on a Macbook Air OS X 10.10.3. I tried Firefox also but same problem. Any help appreciated!
