Changelog:

• Fixed so it more better randomize the locations. It should be even better now and it respect your min value (so players not end up in spawn).
• Fixed so players not end up on nether ceiling.
• Fixed so if you are in creative or spectator and run the command it should now set back fly.
• Added command rwild as option.

I has check if is something wrong with permissions or commands and it working as it should. Don't use rewires as it was support, because I can't give support that way efficiently.

Keep in mind you need a permission plugin and you can't use op.
