Wow, it's absolutely wonderful how moddable SEV is, the vast possibilities available in the data files!
It's great that we can now have system gravitational shield facilities that stop other empires from using stellar manipulation, but doesn't stop your own empire. In SEIV we had to use the gamey tactic of scrapping our own facility whenever we had to create our own warp points, and then quickly building another one that we had on a suspended build queue.
By the way, in SEV do we have the ability to turn on and off these abilities without having to scrap and rebuild the facility each time?
