Engine Crash on Saving Blueprint [v.4.5.1]

Development World Creation
, , , ,
1

I was attempting to save an actor blueprint I had made. It had worked with 4.5.1 just fine before yesterday evening. I have narrowed it down to this exact asset. I even attempted to remake asset but it continues. This is what I believe problem is:

 [2014.10.27-03.55.39:071][536]LogWindows: === Critical error: ===

Here is saved log:

This happens to me also.
I discovered that content are messed up (if i click on content engine crashes) so i just did it again from scratch, this was annoying but was only way. I try even to rechild blueprint but was useless.
