One of the values on my leaderstats does not save

Hi all, this is a script I have for the leaderstats to save, the local knockouts saves, but the local wipeouts doesnt. Is there anything seemingly wrong with the script?

Your problem is that inside the onPlayerAdded function, you have an infinite loop:

while true do
	task.wait(300)
	wipeouts.Value += 5
end

Because of this, the loop blocks the rest of the code from running, so the DataStore loading part never gets executed — that’s why XP isn’t being saved.

The fix is simple: you need to run this loop in a separate thread so it doesn’t block the rest of your logic. Replace it with:

task.spawn(function()
	while player and player.Parent do
		task.wait(300)
		wipeouts.Value += 5
	end
end)
