Guild Wars 2

Normally it is impossible to create any kind of siege (like Trebs, Catapults, Arrowcarts … etc.) in the starting-zone on the WvWvW map. If you try to setup a blueprint, you receive a red error-message, so you cannot place it there. Very well.

How the exploit works?
Open a blueprint, move outisde the save-zone and throw the blueprint on the outer edge of the save-zone, where the [Determination] boon still is active. Make sure the building-site is nearly completely inside the zone and only a few cm are outside.

When you come with supplies, you cannot build it. But as a few cm of the building-site are outside the save-zone, you can come from there and build it up easyly. Once the siege is up, it can be used without restrictions. And it stands completely in area with invincibility-boon.

Would be nice if you could fix this asap
