chunk loader = $5
quarry = $10
not sure on the link modifier, I'm thinking like $10
No, even when using chunk loaders I wanna keep them as small as possible. If you change them all to spot loaers you can have 10 chunks loaded which = 10 more people on the server if, you have them all setup. Which is a bit much for just one person.
I'll look into your diamonds, can you use a wand of equal trade to change it all back?
