Talk:Active Stone Block/@comment-4647175-20120103190156

i had a big problem as all ways i try to upgrade my defenses and i added sand on a active block i wired it up and when i fired it up nothing happened the block activated ( or deactivated depending on your point of view) and the sand didn't fall i am guessing it is because even deactivated ( i will just refer to it as dead or alive from now on)it is still a block. but having a blockade that you don't need to rebuild every time could be useful.
