[TxMt] CSS (overtype broken/removed?)

Before the last update I could type something like:

div { color:red; }

And all was well and good. Now TM throws a space in automatically which is fine. I just have to get used to that. But now I can't overtype the semi-colon. I used to be able when I got to then end of the statement type ";" and it would overwrite the one that was already there and place my cursor outside the statement. Now it puts 2 semi-colons and i'm still stuck in the statement.

div { color: red;; }

What happened to the ability to Overtype the semi-colons in the css context? And how do I bring it back?
