The version showing the extended title with the first line always requires a punctuation.
I'd not played much with the new interface, but if it's not using the same rules, it's a little annoying.
I guess the biggest annoyance is that it's breaking some of my ads* which isn't in itself problematic - I can see the logic in testing this sort of thing, but they didn't warn us about this one so it feels a little more unexpected to have to check and alter copy without knowing the rules.
*Yes, I know that in general it's better not to split a phrase over two lines, but I like to experiment, and for some ads at least I am confident that it will always place above the SERPs and therefore always display on a single line anyway. YMMV.
