Original SeaBlock updated to 2.0. Unofficial fork of KiwiHawk's Sea Block (MIT), fixed to run on Factorio 2.0 with current Bob's (2.1.x) and Angel's (2.0.x). Also adds a stone-based pipe recipe.
I can't really start a game with this mod because the second technology, wood processing, cant be researched. It's not a trigger technology but it also doesn't have a list of required science packs. This happend in any of the combinations that I tried, including just this mod with it's mandatory dependencies and default settings.
