Encounter with Slesha - stuck on "waiting"

Well, as the title says, after encoutering Slesha, i choose "continue", then "let things continue", and now the encounter does not seem to keep going. I had a line of text following my choice, but nothing more, and the "action box", where i can select my next action, has disappeared, and is replaced by a "waiting" text. I'm afraid to refresh the browser, since i dont want to recreate yet another time my character.
I think i'll end by refreshing, but maybe its something else than my browser. Which is firefox btw.
