Despite having the experience percentage set to 75% XP restored on retrieval, no XP is given to the player once the grave is retrieved. Both mods are installed for the client and the server, and the client config matches the server config.

Server config:

{
"mainSettings": {
"enableGraves": true,
"enableGraveLooting": false,
"sendGraveCoordinates": false,
"minimumOpLevelToLoot": 4,
"retrievalType": "ON_USE",
"dropType": "PUT_IN_INVENTORY",
"xpPercentage": 0.75
}
}

still an issue, no matter the "xpPercentage" value.
