During game when I was rebuild some areas in my base I destroyed power unit for trains. Now all electrical trains wants to be charged with coal. Old trains have now 150 coal inside and new trains are empty. Even when I build again power unit then trains doesnt wanto to be charge. How to fix that?

Sounds like quite a few things went wrong.

I've pushed a bunch of changes in an update that should fix all the coal issues.

However, I'm not sure about the trains not charging when they're new. That part is very odd. The mod update should cause some things internally to be reset so that might fix it.

My trains were out of power too even though I had a control station with sufficient power. After a long time of trouble shooting I found the issue: Only the trains which I did not place on the rails by hand were affected. Both the control station and the trains needed to be placed by hand. (For automated construction I use the repair turret mod. That mod and this one seem incompatible.) Thank god, I found the solution, because I love electric trains. Thanks for keeping the mod alive.

This sounds like a proper bug. Looking at the code for the main repair turret mods (the original by klonan and the repair turrets 2 fork) it should all work fine.

Can you please specify the exact mod for me? I did try to do some testing but I don't understand how to make the repair turrets build things. Could you explain how to trigger that so I can test it?
