When users try to destroy a jack-o-death or mine most (99%) it looks like it breaks but then "reappears" with the block and you cannot break it (effect is still working also). If I do a /ps clean it cleans it up and then can break the block fine.

So in short breaking a mine or a jack-o-death orphans the field most of the time and and it takes a /ps clean to fix.

Thanks!
