[Q]

Thank you again Phoenix-D for your quick reply.
One more of the mysteries of Starfury and I am a terrible curious person.
I will try your advice to create the one way warp points.

One other thing I realized in my very limited modding experiments is that Starfury is far less error tolerant than SE IV. I had a black screen after the initial campaign creation without any usable error message: access violation of starfury at adress ......). What turned out to be the cause: in the maindisplay.txt file I had two lines of "paragraph 1" instead of "paragraph 1" and "paragraph 2".
Never would have guessed that the display textfile could create such serious malfunctions of the game.
