Protection against throwing gem into nether portals
Recover gem from mobs when they would be despawned by chunk unload
Avoid tricks via other flight-using plugin to get permanent fly (e.g. Lift)
Configurable logging level in config.yml
Recover gem when it is lost directly in fire or lava
More consistent logging information

It is still possible in some situations for a mob to pick up the flight gem and despawn with it. If this happens the gem will be restored next plugin load or can be manually respawned with /flightgem by an administrator.
