I know about the issue with the drengin super ability, i just never realized how extreme it could be.

In the the last 10 turns of my current game the drengin decided to attack 3 other races. After attacking the first 2 they already had an impressive fleet of 19000(!) ships. The first turn they declared war took about 3 minutes. the second time it was more than 5 minutes. I thought the game was frozen, but just before I lost patience it continued as usual. Now when they declared war for the last time, I waited for 15 minutes than left the computer for another 15 minutes. When i came back my turn had started as usual. So i checked the drengin stats. They now have 45000(!) ships! (Their economy is runing a debt of -84000bc per week.)

The most impressive thing is that the game still runs fine. The ai turns take a little longer but still less than 20 seconds. This just shows how stable the game is.
So if your game seems to be frozen just give it a while and it might come back.

Does anyone have an idea how I can attack the Drenign? I don't think I want to wait for 2 hours to take their lousy 20 colonies.
