I have a small mountain I'm trying to level (30-40 blocks high & multiple chunks square). I tried using colums of TNT. The first (top) one goes off fine but the others won't chain react. Blows up the rock, leaving the TNT behind. It's a pain to set & light one at a time. Tried setting them side by side with same issue. Has TNT been Nerfed to reduce lag issues, or is there some other problem?
