Crashes once more

Hey guys, I have a serious problem which I couldn’t solve yet. A child class of character causes constant crashes. whenever I delete it, the crashes go away but the references inside of other blueprints are gone, of course. Now, when I do a new child, everything is fine. Whenever I set the missing references to the new class, it works. But only til I shut down unreal and open it anew. Now the problem is there again - every blueprint I doubleclick causes an unreal crash. I literately checked every single reference of this object, but no matter which one I reconnect, Unreal crashes. Yesterday, it worked all fine. Since we work with svn,I could just revert all of my progress. But it doesn’t seem to be my fault. Any ideas?

Fatal error!
