Go back to your campaign Save
Launch Stellaris and load the save with the DLC and mods it was made with.
What works in game
I've checked these in game on the versions listed in Supported game versions:
- A moved system sits at its new position with its lanes.
- Fleets can use a new lane in both directions.
- A cut lane is gone and routes go around it.
- A system you isolate stays without hyperlanes, and the campaign keeps running.
- You can keep playing, save in the game and open that save here again.
