Type: trick

containment box can hold crates to carry more stuff by stacks or another containment box, which makes it so closed demon core after 3 containers is almost as safe to carry as uranium block.

part of me tells me that this should be illegal and too easy
but other lazy part of me wants this so it would be easy to carry lots of stuff

and if you are reading this... will it be better if sliding blast doors to destroy low hardness level blocks like leaves and do not close when harder blocks are present? i am trying to implement it but i also want to make it so door will go up again if hard blocks are in the way in stead of not responding to right click, but i cant figure out where is animation triggered and what does sending custom packages to client does (could be source of animation i guess.. )

I think pretty much everyone already knows this
