2013 is eating last char in opened file

I encountered strange behavior.
Sometimes Idea eats last char from my newly opened
class - this is for most cases '}' sign, so that file
cannot compile anymore.

It's very annoying but neither I cannot deted the reason
nor I can't provide a stacktrace to Jetbrainers so that
they can fix it.

Have you encountered similar problems?
