Hi guys, im new here, hope im not posting in the wrong area, hehe. Well, i bought an vps to host my minecraft server to play w/ friends, but im having a few problems. The first one is that whenever im offiline generator or other machines doesnt works, my mfsu was at 2,900,000EU and suddently when i logged, was 120 and kept changing! Whenever i put an nether ore into the macerator, it does the job but when i get the dust from any respective metal that ive put in there, it kinda like back the the ores and it repeats the same thing over again. Hope you guys can help me!
