There was a bit of a bug that I didnt catch where the mod was only working on my pc in its unzipped state - should have done some proper testing before publishing, which I have now done.
Under the new 1.1.2 version just do the following:
- Install the mod (should automatically install the seablock meta pack as well including the two mods I initially said to disable - they are taken care of internally now)
- go to new game -> Factorissimo - Seablock / basic (under Mod scenarios) instead of freeplay or sandbox.
