Have you assigned the tradelane_space_name things for the end rings correctly?

This one is from New York:

[Object
nickname = Li01_Trade_Lane_Ring_16
ids_name = 260920
pos = 3628, 0, -52369
rotate = 0, 30, 0
Archetype = Trade_Lane_Ring
ids_info = 66170
next_ring = Li01_Trade_Lane_Ring_17
behavior = NOTHING
tradelane_space_name = 196776
reputation = li_p_grp
difficulty_level = 2
loadout = trade_lane_ring_li_01
pilot = pilot_solar_easy

[Object
nickname = Li01_Trade_Lane_Ring_17
ids_name = 260920
pos = -70, 0, -58894
rotate = 0, 30, 0
Archetype = Trade_Lane_Ring
ids_info = 66170
prev_ring = Li01_Trade_Lane_Ring_16
next_ring = Li01_Trade_Lane_Ring_18
behavior = NOTHING
reputation = li_p_grp
difficulty_level = 2
loadout = trade_lane_ring_li_01
pilot = pilot_solar_easy
......

[Object
nickname = Li01_Trade_Lane_Ring_20
ids_name = 260920
pos = -11163, 0, -78469
rotate = 0, 30, 0
Archetype = Trade_Lane_Ring
ids_info = 66170
prev_ring = Li01_Trade_Lane_Ring_19
behavior = NOTHING
tradelane_space_name = 261658
reputation = li_p_grp
difficulty_level = 1
loadout = trade_lane_ring_li_01
pilot = pilot_solar_easiest

As you can see the tradelane has the name: 260920. But if you look that up, it says nothing, so you can just use 260920 for every new tradelane you add. The tradelane_space_name part is the important part that you need to mention right, so in this case 196776 in number 16 is Fort Bush and 261658 in lane 20 is Colorado Jump Gate.

So if you go fom Fort Bush to the gate it will say: Fort Bush -> Colorado Jump Gate and if you go the other way around it will say: Colorado Jump Gate -> Fort Bush.

That's all about naming tradelanes.
