Thank you for playing Economica! Here are some things you should know about the pack...
Immersive Railroading can be difficult to play with for people that aren't familiar with it. Luckily though, Immersive Railroading has integration with the In-Game Wiki mod. So if you can't figure it out, just press the ____ button, or whatever you've set the In-Game Wiki mod to, and there'll be a handy-dandy guide on how to do stuff in the Immersive Railroading mod.
Economica has Tinker's Construct. It also has Tinkered Hegemony. Tinkered Hegemony disables all vanilla tools/weapons, forcing you to use only Thinker Construct for your tools and weapons. It also replaces vanilla style tool and weapons in the recipes in other mods that have a vanilla tool as an ingrediant. Please notify us as soon as you can if you see a recipe that's still set to a vanilla style tool/weapon so that we can try fixing it using CraftTweaker.
