It's really strange. The traits I'm choosing are almost the same as my first character. Alien race with the traits: Accurate, Elusive, Efficient, and Warp Theorist.
I just tried without the proxy, but it made no difference, since I had changed that to start using one after I made my first char. Without the proxy, I get lots of lag, rubberbanding, and disconnects. The only difference with my first char is he has Techie rather than Elusive.
I'll try just for S&G with different traits, but it'll take me a bit, as it wants to do a full scan after every crash, which takes about 10 minutes.
