Hello i am interested in this and i have sent you a PM

Making a sandbox mode train base for fun and idk which one :C

I want to add a recipe that does a type of ore refining that does this (this recipe comes with oil processing), in a chemical plant , put 5 ore and 10 light oil , get 6 ore , put 6 ore and 10 heavy oil , get 7 ore , put 7 ore and 10 petrolum gas get 8 ore , i want a example mod that i could work ...

Thanks for the report however we've never said every one of the presets would let you unlock all achievements. Just like the expensive mode doesn't let you do the no-hand-crafting achievement.
Railworld is a preset made by the developers , anything lower than normal(for ores or cliff water etc ...

I agree , considering railworlds are a preset.

**ONLY WORKS IN SANDBOX** When placing down an entity , you can duplicate it by doing this : when you're down to 1 of the entity you chose , place it down and then immediatly press Q , you will get a whole stack , i have been able to reproduce , it just takes a few tries.

changing factorio_version to 0.16 wont work as soon as you have circuit controlablle entities

hopefully you guys make the merch cheap so i can buy it , even if i can't ill still test out 0.16 asap , might skip school if there's not an important test just to be there when it release , might be nice if you guys release it on the weekend tho
