So I was minding my own business this morning, clearing some land and making room to expand my quarry, when out of nowhere it felt like I was "shoved" to the side, as if someone had walked on top of me. I didn't see anyone and I quickly checked who was online.. Nobody.. I was alone.. I walk a few more steps then turn around randomly shooting my mining laser everywhere. I HIT SOMETHING! I saw flames in the air and a second after I saw shaky_1770 log offline. But.. there was nobody online except me, right? Well.. a few seconds later I saw him log off AGAIN...

What the heck is happening? Is the server haunted? Or is there something more sinister going on?

That is very strange...

Maybe he is a hacker which would explain invisibility

but that doesnt explain how he could log out twice

I think I did see a mod on the MC forums that lets you log in without notification. Not sure though, there's mods for yoo many things.
