Yeah, I just couldn't grab them, no matter how much hopping I did. Honestly, I like doing large loads of Ores, I love when I get 2/3 crates full of Ore. But, pushing all 3 back would take so long I could make enough cash from buying all the ingots that ore would make simply from selling tools.
Oh, also, how do you get more light sources for the cave? I want to set up a long line of them going from the mine entrance to the central cave so I don't have to walk blind till I see the crystals.
