A Doubt with the Arborec Racial rules.

By Mentak lagarto, in Twilight Imperium 3rd Edition

Hello to everyone! Hope you can help me with a doubt we had last weekend.

We've been playing TI last saturday when a conflict appears among us. The argument was about the built capacity of the arborec ground forces, and its restriction about building PDS. On the one hand, in the FAQ's we can read that the arborec can build SHIPS with their GF units, but in the other hand, in the rulebook there are a restriction about building a PDS (not a ship) in system without Space docks. As a consequence, we had a very long and exhausting dispute.

In order to that, this is my question:

- Does the Arborec ground forces count as a Space Dock in every building cases?. Despite of the Production Card, wich is consigned on the FAQ's already.

- Could I build a PDS on a System not containing a Space Dock?.

Thank all of you for your help.
