sorry I was busy getting my pI to work as media center. Tinker did some proof reading as well. I will check the texts corected by GunChleoc if my story is still ok, although I have little doubt about the translation.
Next I will implement a nice way to give the player a permanent hint about the artifacts. Mainly based on kaputtnik's code and sending a message to the player. Think I will manage until sunday. Thanks to every body.
