Not BER, that is catfacing. Looks weird but the fruit is fully edible. YOu can Google catfacing in tomatoes but it is basically caused by cool temp at the time of pollination.

Dave is correct, as usual. A couple of my Black Krims looked just like yours, but were still absolutely delicious when they ripened...

Thank you everyone! The areas are hard not soft. If the end result of catfacing is still delicious tomatoes then I'm satisfied. It's all I really wanted to know. Great tasting tomatoes is and always will be my ultimate goal.
