I’ve been having trouble lately with a couple of different things.
First, when the links for names show up, not all of them are “active”. When you go into to edit them, the links are there, but they don’t show on the post. I have to go through and add a character, hit save for the links to activate on the post, edit again removing the character and hit save again for the links to show without odd characters. Most of the time I notice it is the first name in a paragraph, especially if it is the first word of that paragraph.
The other thing is tagging someone. I’ll start typing @name, and potential names will show up. I’ll click on the name I’m looking for, and it will leave me with the partial name I typed, but won’t fill in the rest of it. I don’t always notice it until I hit the save button.
