Issue: Can delete/move lines and tank symbols but cannot create new lines nor tank symbols on a briefing
I've tried refreshing the page, refreshing the browser, even restarted my PC but still can't create new lines I've also tested out logging my account and trying a guest account and it can't create anything as well
I can create new lines in a new briefing but cannot in the old one
Seems like the briefing itself is bugged
