Honeybee weird bug when creating zones

Chris and Mostapha,

Now this seems to be a very weird bug.

I ve been trying to figure out what is going on for the past 10 days!

When there is a zone with a core in the middle, with rectangles referenced from Rhino or generated in GH, if the center rectangle centered to the outer rectangle the adjacency are not solved properly.

It seems to consider the inner walls as outside walls and make windows.

If you move the inside rectangle even a little bit, then it works!!!

Really a mystery!

I attach the relevant file for you to investigate.

Thanks,

Dimitris
