How did you complete the part of building train tracks to the new Forest Horizon Point base?

When i built the tracks and power there, i only got credit for getting power, but it didnt complete the part of repairing the tracks to the new base?

Right now my train is sitting in the base, and it has power, but im stuck on the same objective: https://imgur.com/a/usw6Na5

hi, try to build tracks and power line simualously, sometime there is bug in train schedules (maybe you can actually control the train, im not sure now)

probably some other mode just killed this script

Thanks for your reply. This was one of those issues I did not understand at all until I solved it accidentally. Your logic was sound, I just messed too much.

You see, at the start I got so sad when the debris hit the first base (right when we get the train to the base), that I reloaded and got the base to build me a rocket launcher before I connected the train. That's why I removed the inserter and belt to the assembler at this base, to stop them from making a(nother) rocket launcher for me.

And it turns out that was the trigger for the next objective...
Maybe make them all unmovable?

Thanks for the reply! Much love for the best mod in the game, this gives a totally new purpose to the game! 👍❤️

This was the mod list I used when played mission 10:
