SafeLogin

Login protection, invulnerable (no damage), invisible (no mob tracking), un-pushable while in the same block you logged in on. You are still pushable by fluid like running water, and it will disable login protection and if you log out in an ocean, it will disable as well (moved off the block you were on, y-level), so long as you log out and log in on a solid block, you should be fine/it should work as intended, if not, open an issue.
