I think that minecarts with hoppers should be removed on skygrid in the first place. They can bypass locked chests, and someone set home in my vault. I lost about 5 stacks of emeralds, 4 stacks of diamonds, 2 stacks of iron blocks, and a lot of redstone. That was all my belongings and now they're gone because someone set home in my base and raided me with the minecarts.
Mook, I'll give you my kit. I get quite a bit of redstone and cobblestone and some other things with it, it'll help.
