https://github.com/Melonslise/Locks/blob/a91573c100dbba32badd9166bf7542bd373faa5b/src/main/java/melonslise/locks/common/event/LocksEvents.java#L120

uses a randomly selected size rather the value set in the configuration.

Alternately, if this was intended, it would be great if you could configure the upper and lower bounds of the locks.

Yes, it was intended. I’ll try to add the requested feature at some point.

Enjoy!
