I had same issue this morning. If yours is same as mine was, when it sends you back to city menu, click through options to talk to Elly and confront Ven again. Should work properly on second try (as side note, this only works if you go straight to this when the menu comes up after fight. Doesn't if you go anywhere else first, including sleep)
Annoying have to do fight twice, but at least it's a way around bug until it gets patched.
