Within the past week I have noticed that i see a fleeing ships jump cords only 1/2 the time when i'm within 1000m. Did something change in game?

Oh you mean jump destination? No, that shouldn't have changed.

Yes, jump destination. I'll try to get video of the game not displaying where another ship jumps. The issue mostly pops up during player vs player chases. I've been at 500m and never get their destination cords.

FYI When sector hopping, if the target's jump initiates before the chaser enters the sector, the chaser won't see the destination even though you can be well within 1000m. Could this be what you're seeing? Personally I think if you can see the ship still and are within 1000m you should see the destination.
