I don't think corium damage is disabled, I was messing with 3 nuclear reactors, and I made them melt down. after that, corium flooded a room underneath them multiple times after I tried to patch the holes.VanessaE wrote:They can get laggy, yes, but mostly because motors and frames can be used to move things like node breakers, such that they can cut wide, practically unlimited paths through the landscape without any recourse.
Last time I had them enabled on this server, someone used them to cut a 5x5 or so trench nearly 1000 nodes long through the map. I had to repair the damage mostly by hand.
Lava/water (and their cooled results) can be worldedited-out, corium damage is disabled since the server is set to disable damage otherwise, and pistons/movestones can only move a limited amount of stuff, so their ability to do serious damage is pretty limited.
Maybe you could limit the use of frames by limiting how many can be attached together, or not allowing them to move node breakers.
