Gamerule keepInventory false doesnt works!

Hey guys,

I have a problem on my sponge 1.12.2 server:

I want that keepInventory is false but it doesnt works, the players still have their inventorys after they died.

My plugins:

  • Nucleus, UniverseGuard2, LockPerms

Mods:

I already made /world gamerule keepInventory false and /gamerule keepInventory false and the server shows that too.
What can I do?
