I did the ol' copy and paste. The first time I did the whole base, and all worked well. The second time I used the top section or "Base". I didn't use your ore fields I did the outpost mining. Problem being all the trains just sit there won't go to [C]. HELP, please. So far I love STM and your Mega.

Can you try to edit the train schedule and remove the stop at a specific position [X,Y] with condition (fluid < 0) ?
You can then route the trains to the station you want ?
There is also a command to fix some freeze case:

/stm_unfreeze fix

If all of these fail to make the base working, can you give me access to your saved game ? i will investigate

It's just not working for me. Still have to wait at each station an "stop at a specific position [X,Y] with condition (fluid < 0". I'm going to TSM. But thanks for the mega base.
