THIS MOD IS DEPRECATED: I started a new, but similar project called ick's Sea Block Pack.
This mod is an addition to the SeaBlock mod pack. It removes things like mining drills, pumpjacks and equivalent research since they are useless in SeaBlock. Replaces vanilla concrete and refined concrete with concrete bricks and reinforced concrete bricks from Angel's Smelting and removes the bob valve in favour of the angels valves. Also rearranges some recipes and changes some recipes so they use the previous tier as an ingredient.
Known issue:
Vanilla concrete and refined concrete items are not migrated. In order to change them to concrete bricks or reinforced concrete bricks you have to place them down and mine them.
It is the first mod I've ever made. If you have any idea how to improve my mod, please contact me.
