As title says. You've replaced cannon damage bonus for your custom heavy cannon shells damage bonus, removing vanilla cannon ammo bonus damage from research. Please fix, or merge those two ammo types into the same category.

Also Locomotive requires steel to make, but Train tech does not require steel processing research. Can you add that to prerequisites? Same with the bigger storage chests items and technology.

Thanks for the mod, I'm having a blast playing this!

Thanks for the feedback! Sorry, I missed this bonus. I will do this in the next update. Technology will also be improved.
