Im positive I had a fuel source - aeternatis fuel. We can all see the thing it shoots but once it hits nothing happens. We can hear the sound too. For plugins, I have all the essentials (except group manager, which seemed to bug out the quarries) and dynamic ban. Later I added disguise craft and voxelsniper, though it wasn't working before I added those so I believe its unrelated to those two. Should I try deleting all the plugins? Oh, and yes, Ive tried it close and further away from spawn. I haven't tested all of the items, but those are the two Im sure about. Also, the transmutation tablet seems to work just fine for me...
