Title is fairly self-explanatory. The Dread Lords made an appearance in my game today, but to my disappointment, they were right next to Earth, meaning that they were likely to be wiped out before doing anything. I tried to get the Terrans to make peace with them until things could get interesting, and surprisingly, the Terrans agreed. While this is good (sort of, they're building up fast) from a "fun" perspective, I was under the impression this bug had been fixed by now - it should not be possible to communicate or negotiate with the Dread Lords in any way, including making peace with them.
The debug.err had nothing that appears to be relevant, though I can post it if you want.
