what a great plugin. players often complain when their items glitch through the map and can't be retrieved without mod intervention. I added this to my server and players no longer complain of lost items. Well done and thank you. 

Does what it says it does.
Saved backpacks and active items of players multiple times.

I mean, it does not happen often, but WHEN it happens, this plugin saves the day.

I got this plugin because sometimes the backpacks players wear falls through the ground. I tested it and tried forcing the items through the ground and it brings them nicely back to the surface. you also receive a notice one of your items tried to fall through but its been resurfaced. I really like this plugin and every server owner should have it!
