1- Warp Interdiction function does not appear to work. With a level 2 interdiction system set to maximum interdiction range active in the same sector, a ship equipped with a single-block reactor is capable of easily charging its drive and jumping out of the sector.
2 - Warp interdiction on stations is impossible, as there is no way of activating the chamber.
3- Warp interdiction when the entity is unloaded (necessary for creating defensive perimeters or 'walls', or functional NPC/AI interdiction ships in fleets) does not function.
