Updated the script finally.
Should now take kegs even if the keg holds more than it can contain and give back same keg now with remaining left.
Will now invalidate properties every time UsesRemaining is updated so it shows immediately.
Remember to always test on a test server for bugs before adding to a live server (in case of crashes or corruption).
I also had all items deleted before rebooted in case of any problems i don't know if any could cause though from the changes made but maybe.
