What happens with beds if tnt explosion damage is disabled? You should make sure that servers are still able to disable beds.

If protect.prevent.tnt-playerdamage is enabled, then TNT doesn't do damage but beds still do.

If protect.prevent.tnt-playerdamage is enabled, then TNT doesn't do damage but beds still do.

Sorry if not clear, what I'm really asking is with this PR are servers able to both:

• enable tnt damage but disable bed damage
• enable bed damage but disable tnt damage

Just want to make sure because this was catching both before, but it should be possible to control them individually. In addition, you should check that any other exploding blocks are handled correctly too.

The PR just means that the config option for tnt damage only disables tnt damage and not bed damage. I can add config options for bed damage if required?

Would only be required if the change breaks behavior that previously was expected.
