Have a new server with FTB Direwolf20 installed. Along with that is Essentials, MCPC+, Grief Protection, Multiverse, World Edit, WorldGuard. Created a mine world and teleported to it no problem. Set the spawn point and then fell through the floor. Teleported out and back and samething happens. Did a restart and once again fell through. It seems to happen after about a minute. I can interact with blocks and build. No error message seems to come up. Any idea what would be causing this?
