The infinijump occurred long after we did that, and we used jhs without problems after we did it. I first noticed it when I used the alien gate in iota on a nomad (no jd). From the time I noticed it and the time the server was reset, I think I may possibly be the first (or one of hte first) to have experienced it. So maybe those alien gates have something to do with it? It was a while after we stopped jumping around with docked ships though. Since the bug is so hard to track, there is probably a random element involved, or something that occurs after several cumulative occurrences, not just one occurrence.
