Curse you and your challenge!

I made it to 2409.6 of game time. Looking at the score screen when I first began the game I knew it would be tough just to survive out here; so I took a different route then most players would. I build a warp opener/closer from the start and I have now cut myself off from the Sharks. I had made first contact 9 turns into it!

After closing off contact I continued my expansion process colonizing all available - oh and I will have me a ringworld in a few more turns - when I get a message saying that one of my planets has been destroyed by the Sharks. I'm thinking, "what the heck?!" I didn't even see a ship in any of my systems. So I think well no big deal and I continue on; then it happens again!

After 3 more times such as this, losing planets without ever seeing a ship in any of my systems I finally build some sats that can detect cloaked ships; but to no avail! I have them in all my systems but for the next 3 turns I lose planets!
I finally have to start abandoning some of my planets because I do not want to lose them. So I do so and I continue my search for whats doing this. I lose yet another planet and I decide to take another step; put mines on all my planets. So I do so and 2 turns later...BOOM! I finally caught the little son of a beach. I still, down to this turn, cannot figure out how he was able to get under my sensors and get to my planets without my seeing him at all.
But the problem is solved and I am happily growing once again. I haven't seen the Sharks use warp point openers just yet but I'm sure it will be coming.

Great job so far on the callenge Stone Mill and I look forward to continuing this game onward. Speaking of which.....

I think...therefore I am confused.
They were armed. With guns, said Omari.
Canadians. With guns. And a warship. What is this world coming to?
