What I did: created a Person by using the “@” tag, then changed my mind by using Option-Delete to remove the word.
What happened: Agenda crashes to the Desktop every time.
What I expected: the text editor should delete the Person tag (word).
Things that might be helpful to know (Agenda version, OS and model, etc): this has been going on since at least 1.0c2. High Sierra 10.13.2 (17C205), MacBook Pro13,2
