So, I have a capability storing some data, so I want to keep the data when the player dies (if resetOnDeath is false) or when he comes back from the end dimension.

Here's my code:

    @SubscribeEvent
    public void onPlayerClone(PlayerEvent.@NotNull Clone event) {
        if (!event.isWasDeath() || !ServerConfig.resetOnDeath.get()) {
            Player original = event.getOriginal();
            original.reviveCaps();
            original.getCapability(PlayerCapabilityProvider.PLAYER_CAP).ifPresent(oldCap -> {
                event.getEntity().getCapability(PlayerCapabilityProvider.PLAYER_CAP).ifPresent(newCap -> {
                    newCap.setNBTData(oldCap.getNBTData());
                });
            });
            original.invalidateCaps();
        }
    }

Event is registered though the Forge EventBus, registration is located at FMLCommonSetupEvent.

When testing in a singleplayer world, everything seems to be perfectly working. When I join a server however and die, the respawn button does nothing. Any ideas?

PS: I'm using latest Forge version 43.1.43 for 1.19.2.

This is badly formatted.

Do you mean the respawn button doesn't work? Or that the data isn't copied?

I mean the respawn button doesn't work at all. Nothing happens when I press it.

Can you check your debug.log to see if there is any error occurring when you press the button? Nothing in the method provided immediately jumps out to me with an error.
