Dredgeworks allows for modded oil-like resources to spawn on water, but doesn't provide any way to mine them without just landfilling over. It would be nice to get some dedicated machinery for at least popular mods.
This is more of a pressing issue when map settings are tweaked to increase water coverage and/or using mods that prevent landfilling deep water (e.g. Depths of Nauvis)
Affected mods:
- Krastorio 2 (and Spaced Out) - mineral water often spawns on the deep water. Unlucky seeds with high water coverage can result in practically all mineral water being underwater, blocking the progression
- Deep Core Mining - Deep Core Cracks spawn on water pretty often. This one can maybe get its spawning disabled on water?
