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 published a small temporary compatibility mod for Sea Block Continued 0.6.3
that replaces the unobtainable Nickel Plate requirements left in several
reachable recipes. Sea Block Continued is created and maintained by darkenade;
this unofficial patch is expected to become unnecessary once the main mod
incorporates the upstream correction.
