Hi 3image,

re:

It's because it is a very complex area of code and some things like adjusting tolerance values for what to consider intersecting or not intersecting can produce side effects like causing other things that used to work to now fail.

So it's in an area that would need first a huge intensive effort to properly figure out exactly what is going wrong, and then followed by another huge intensive effort to test a whole lot of other cases to make sure it doesn't cause regressions in other cases.

Basically it's not going to be the kind of thing where it's a typo or simple logic error.
