This is the correct version 3.0.6.4. I apologize to everyone who downloaded the preview version of 4.0 before. As it had a safety feature on it to prevent operation, please just delete it and use this one.

Reminder: Version 4.0 when it comes out will only support Java 8 and we will be dropping official support for 1.7.x servers, so upgrade today!

Updating
If updating from 3.0.6.x, just copy this jar over the old one (after taking backups!). Otherwise, follow instructions for V3.0.6.

Bug Fixes

• [Medium] Console errors when teleporting to island world, or if config.yml does not contain all the settings in the protection.world section. Could also cause errors when saving the grid.
• [Medium] Island reset/leave commands were being executed on the old leader when makeleader command was run.
• [Medium] If players had bad non-numeric settings for numeric permissions, like team.maxsize.x, island.maxhomes.x, island.range.x, island.multiplier.x, console errors could occur and island protection range could be set to zero, resulting in players not being able to interact with their own island.
