EVE Online's Tyrannis expansion had brought with it several broken features. While the planet-scanning interface works fine and looks fantastic, the deployment of command centres was pushed back until June 8th. The materials produced on planets could not possibly be made until June 8th but on May 26th, tier 4 products from planetary interaction began appearing on the market. It wasn't long before EVE players figured out that you could refine NPC-sold starbase structures into high-end planet products. Starbase structures are one of the many things that CCP is switching from being supplied at fixed prices by NPCs to being produced by players through planetary interaction. The NPC supply was meant to be removed on May 26th but as players were currently unable to produce the structures, that change was delayed until June 8th.
