Condition fullfilled to early but only "sometimes"

[jonas.thornvall at gmail.com]

I've been looking at the code for two days so i am a bit crosseyed.
If anyone could help me set the condition so the loop catch the last pair/pairs, it is kind of weird that it succeed sometimes and break to early and report fail others.

I would be very greatful if anyone can see why it break to early and return fail. Although it is clearly a succes looking at the last remaining pair none connected pair.It should report fail for the network permutations that stall due to link exhausting, but not stall creating last pair.

It just a minor bug due to some condition that i just not get.
Have a go 5 munutes maybe someone catch the faulthy condition.
