Strange & silly issue when routing

I attached my radio project with .txt(but you need rename it to .dsn) for you.

When width=0.5mm & spacing=0.25mm, i found it falls into a strange loop with the network Q1_3.

But in fact, it just can routing by human easily without any holes. So I think maybe it can reflect some algorithm bug or disadvantages.

You can see the first time, this system is quickly stopped with "auto-routing completed" but we can found network Q1_3 was bad.

And we try to restart the auto-routing, but we falls into a infinty loop with increasing processing number.

but if we just look for Q1_3, we will find it just need a simple connect without any magic.

Maybe a special crashed judge program thinks the circult without Q1_3 is also correct ... ?

In my computer, sometimes it will loop infinty, sometimes it will just enter optimizer and stop the auto-routing without routing Q1_3.

So I just thinking: Did freerouting not see Q1_3 was incorrect? Or it think there's no solution of it?

Anyway, there must be a bug. And I think it was a impartant bug.
