Describe problem (what you were doing; what happened; what should have happened):
I tried to set the teleport.survival from 16 to -1 (in order to allow survival teleportation and ignore distance) in the config option from the mod options. However it keeps setting the teleport.survival to 1 and i could not teleport at any distance.
