Fuck you Jira, for your shitty implementation of the board, which causes written comments in tickets to simply disappear.
You clicked on another comment during edit? Say goodbye to what you have just written!
You clicked on the send button to send your comment? Well, many things can happen with our overcomplicated pile of shit that we call Jira. So, your comment might get lost. Fuck you. We are complicated. This shit can happen. Deal with it.
