Looks like they are in a vanilla world. Just explore.
I can’t even begin to tell you how many times I’ve done this.
I did it yesterday. Twice. I have since fixed my problem, and claim I wanted the obsidian as a backdrop to the generator so I don’t mine out every block around it.
I recommend just putting the water in a reversed stair or i think leaves work too tho thex might burn, that way the water cant flow
ELI50?
A cobblestone generator is supposed to mix a flowing stream of lava with water, by placing a bucket of lava next to it (which creates a reusable, infinite lava source). But Soldier dumped the lava directly into the water, which created a block of obsidian instead and wasted the lava.
I haven’t mined the craft for over a decade, but this is the kind of knowledge that lasts for a lifetime.
