Every time either me or my players rejoin the server the settings reset. Only one of us uses Lenient Death and the rest want to disable it but we need to to enter the command every time we enter the server to disable it.

Think I found the issue; the per player mode wasn't copying over when a new Player Entity was made (death/connect/dimension change); I'll push a fix now

Fixed in 4b92b59

Thank you so much! Awesome mod!
