For use on servers that have a mainly creative purpose, the setting
enable_corium_griefing=false will prevent corium from flowing far or
unpredictably and from destroying nodes other than water. All reactor
meltdowns will stay contained.
Reactor `explosion' now replaces the reactor core with a corium source
node. Corium is a new liquid, which flows a bit like lava, but has
the additional feature of destroying nodes to which it is adjacent.
It also randomly turns into a solid form, chernobylite, which makes an
attractive building block. It thus gradually melts its way through the
reactor shielding layers; a meltdown gets worse over time if not cleaned
up promptly.
The mechanism for an active reactor core to damage nearby players is
generalised into a "radioactive" node group. Corium and chernobylite
are radioactive, to varying degrees. Players receive a varying amount of
damage from a radioactive node, depending on proximity. Staying outside
a reactor cube is sufficient to be safe from the active core, but not
sufficient to be safe from a melted core.
All electric machine recipes now include cable of the appropriate tier
as the bottom-middle ingredient, immediately below the casing ingredient.
Many LV machines were using a copper ingot in that location.
All electrically-powered machines now consistently indicate their
tier (supply voltage) in their names. As this implies that they are
electrically powered, the furnaces no longer have "Electric" in their
names. The fuel-fired equivalents of electric machines, which exist
for alloy furnace and furnace, now say "Fuel-Fired" to distinguish them.
(The fuel-fired alloy furnace used to say "Coal", which was inaccurate
because it uses any fuel. The fuel-fired furnace, from the default mod,
used to just be called "Furnace", which is ambiguous.)
Electric power generators now consistently indicate their tier and have
the word "Generator" in their names. This makes their purpose much
clearer, and makes obvious craft guide searches produce useful results.
The fuel-fired generators, previously just (ambiguously) called
"Generator", are now explicitly "Fuel-Fired".
