Short description of error
I'm modeling something where I need to use boolean modifier to create windows and doors to my model. It works nicely, but now when I created some details to my object in edit mode, it seems that they also works as boolean if they are touching the certain part of my object. If I move them little, they seem to work nicely. I'm not exactly sure if this is a bug, or something else, but no one knew nothing about it, so I had no choice than create topic here.
