This is my favorite mod for this awesome game as well.
Ok, not sure if anyone else has reported this bug as there are 300+posts before me, but in singleplayer and multiplayer, if I fire a deliverance signal it will cause the game to minidump.
My friend and I were playing with the DS mod in, I as Advent Rebel (I've never really tried anything else) and him as TEC, against TEC and Vasari AI opponents. He asked me to fire at a planet to help him take it down, I complied, building the Engine and watching it so that I could fire it directly at the desired target, rather than it firing off on its own randomly.
As soon as it was completed, I lined it up and fired, he and I watched the signal right up till it hit the targeted planets gravity well, at which point we both had a minidump occur simultaneously.
In my own single player game, I got to the point where I could use the Engine, and built one. It fired, I found the signal before it hit, and when it hit the target it was aimed for, I minidumped.
I don't know if that is of any use to anyone, but I figured if it could be a DS related bug I should post it. If I could help out more, please tell me how.
(The version of DS we are using is "Distant_Stars_(R)_ALPHA_0.11_" & Rebellion v1.1.4480) <That may be very relevant, not sure if there's a newer version of either, currently.
I said 300+ posts (should have been 8000+ posts)
