I'm having a weird problem with the V carving operation.
For some reason the operation goes outside the selected vectors. Sometimes its fine, and sometimes it decides to make an extra cut somewhere outside the line.
First image: Just as i want it
second image: same file, same operation but rotated 90 degree. somehow it goes wrong
third image: here you can see the line going outside the vector.
It must be a simple fix but I can not find it at the moment.
