Assuming I entered everything correctly, this list is not preventing Nuclear Generators or Nukes from wiping out a claim. I did several tests with this setup loaded, made sure the ID's were proper. Made a regular claim for myself and an admin claim next to it. Then set up a reactor to blow up. It ignored the claims completely and just left a gaping crater. Doing the same with regular TNT, with surface explosions turned on, resulted in an explosion that left the claim intact.
So what is the 'explodable' list supposed to do? I assumed it was to identify which blocks generate an explosion so GP can then block them or make them follow the claim rules. Is this at all possible or should I just turn off explosions for reactors and such?
