Ctrl Z gives an unexpected error and randomly removes closing bracket

[AnataBakka]

version 6.3.

manually type something like

and then do ctrl z. After a few ctrl z-s the editor will prematurely remove the closing bracket of void main(), and after further ctrl z-s it will show up with this error

you can close the error and continue ctrl z-ing, until eventually the error pops up again, and again, and again...

another issue seems to be happening with ctrl y. first undo everything with ctrl z. then ctrl y and you will sometimes get stuff like this

if it doesn't happen just undo back, and ctrl y again, until it eventually happens

I have got the same problem too. It bothers me a lot.

note: from what i've observed the above undo seems to break because of the automatic indent. disabling these options seems, so far, to make it safe enough to undo
