blender 2.78 problem with bridge edge loop When cutting a hole in the plane, I got into this problem.

v. 2.78


In the previous version of the blender (2.7), this problem does not exist.

v. 2.77
It appears to me that if you select all of the vertices of the hole you are trying to cut, and rotate them 180 degrees on the y (green) axis, you will solve your problem.
