This cannot happen before the Malvolence Arc. Someone earlier said that by doing that it could place this episode the time of confusion following the Battle of Geonosis. The fact that this episode leads into the Geonosis Arc puts a stop to such speculation. I highly doubt that an entire new droid foundry could be built on a Republic occupied world in such a short time. Why would two Geonosis campaigns be so close together if the CIS abandoned the planet shortly after the first invasion?
