This IS a bug right!?!

Ok, I see you point, dmm. I have not tested this in this special environment.
Just for the records and the lurkers, in a normal situation, a ship is either a "treaty" ship (so the AI does not attack it) or it isn't (bash them, lad's!). However, the AI is often much to busy at another place to react in time.
And yea, SGF's are quite powerful, however, don't forget that it will deny all opening and all closing of warp points. In a PBEM game I pla I have just nailed down a very important warp point so my enemy to come has no chance to close it.
