I just tested my reactors with the new system, and I had an accident...
Let me just say the reactor went poof, leaving just shards of the containment building behind... Now the thing is, the containment building was made out of Obsidian, and from past experiences I couldn't dent it with either explosions, not even the nuke.
But now it disintegrated like cardboard and took a decent chunk of terrain with it.
Do I really have no choice but to start building my reactors out of Bedrock?
