I just encountered a segfault while using this mod.
It could be that this mod had something to do with it, or perhaps not.
So with the thought of reducing heavy strain I've come up with not
changing the persistance of the node unless we really have to (i.e.
swap_node then change persistance), this should reduce possible bugs
within the Minetest server thus more reliable/better. (Either way this
code change should help greatly in stability)
If the item is not burnable it will not be eaten (and infinity keepers
will always not eat the item, since regardless it's not supposed to be
accessable)
closes#1
The bug #1 is squashed, the code didn't set super_user to 1 for
`chunkkeeper:keeper_inf_off` which prevents it from enabling itself.
