This is a fork of dumptruckman's chest restock plugin for 1.12.2, now updated for 1.16.5.
Very simply this plugin will refill a chest that has been configured after a set amount of time (defaulting at once every 15 minutes).
the chests must first be set by filling a chest with items, then looking at it and using /cr create, this will save the chest's contents then after an item has been taken, a timer starts for the refill.
To update a chest's contents you can add more items, look at the chest and use /cr update.
other commands can be found with /cr help
