As the title suggest, for the last while, The West AB Passage has been completely isolated on my tech tree, i have little idea whats caused this, since most of the other entries work fine (North behind Secretas, East right before Aquilo, South after Vesta) but West is basicly just disabled.

Hope something can be figured out.

It's probably due to hidden technology :)
If you didn't opened all planets in inner space, before asteroid belt, some exits may be closed
And also, for example, North exit will be opened after Secretas, so no cutouts in the space travelling
If you don't like this approach, you can disable tech reparenting in the mod settings
Also you can suggest any techs if you think it would better fit

makes a bit more sense, probably Rubia and its hidden techs.
Also, i wasnt complaining about the other exits, i like that i have to go around to access the planets, before unlocking the shortcut : )
One small change i would like to suggest is adding Panglea before North belt tech instead of after, as currently the planet is between the exit and Secretas, but after the entrance in the tech tree, i assume this was intended as a ''They unlock together''?

While im at it, a small tidbit:
Can the Solar System edge location be excluded from the planet rotation?
Currently it looks wonky, but i can ignore it if this isnt possible : )

Have a good day.

It's a question for Visible Planets in space mod author, Better Planets does not modify planet rotations
