Somehow I can’t find the reward id to disable the boss fight reward. I need to disable that since it deletes player’s graves and tombstones when they lose the fight and not just the blocks it placed. And that is a no go especially for servers with little kids. Mean it’s a nice and fin reward but the way it vanishes is terrible as it deletes everything in the space that wasn’t there before including any type of grave.

You can use profiles to do this. Unfortunately it's just a bad interaction with Gravestone mods and I haven't been able to think of a fix yet. The rewards don't really "delete" stuff, they just put the area back to how it originally was and because the gravestone gets placed during that restore period it doesn't like it and can clash. Here's a profile with all of the rewards you will want to disable.

{
    "initial_profile": {
        "name": "Initial Profile",
        "description": "Profile that is auto enabled at the start of the pack.",
        "rewards_to_disable": [
                "chancecubes:anvil_rain",
                "chancecubes:math",
                "chancecubes:maze",
                "chancecubes:matching",
                "chancecubes:monty_hall",
                "chancecubes:tic_tac_toe",
                "chancecubes:boss_demonic_blaze",
                "chancecubes:boss_mimic",
                "chancecubes:boss_evil_witch"
        ]
}

Thanks for the help. Never had the problem with the maze for example as I never died in that one. The boss arenas that deleted themselves along the grave when you lost where the problem. assuming these 3 bosses are all I can update my pack now that I took the, out. (Going to use your features to make a few custom rewards to make up extra variety for players.)
I had to ask like this since not all rewards are listed in your wikipage

Thx for the response. (why do the arenas even delete themselves I mean its idiotic to open them in or near your base anyway so if someone overwrites their base like when they get the string reward, it’s their own fault the stuff disappearing is problematic as it also deletes the air blocks inside and the like graves) as long as you don’t use bedrock they can always clean it up later but mostly players open them in a save area away and those who don’t whelp to bad for them.

The maze uses the same system as the boss rewards and can run into the same problem along with the rest that are there. Yep, the wiki page is missing the very latest rewards, haven't had a chance yet to update. The arenas and what not restore them selves out of cleanliness and just because it's better in the end for me. Plus the maze is all bedrock so that one has to anyways. Again I wish I had a better solution.

Sadly i can’t help with finding a better solution have no idea on coding. I can just say I like the mod and thx for the quick help. Will tinker with custom rewards in the future but nothing to big. So case closed thx.
