RR 2.3.5 changes
RR 2.3.5a hotfix

Repaired the internal hosting broken due to a misunderstanding. This will reactivate TabbyChat in the pack.

Note the following:

We load FML then chainload LiteLoader on top of it, allowing us to load LiteLoader mods (i.e. TabbyChat)
Minimum, ENFORCED RAM and PermGen settings are set
Internal mirrors are used to prevent download malfunctions

IF YOU NEED TO UPDATE THE LIBS, UPDATE OUR MIRRORS :)
Further Metallurgy corrections

Based on feedback (i.e. Lambert saying the Iron oregen was "perfect"), Iron-style ore distribution has been applied to other common ores, adjusted for intended rarity. This should result in a net reduction of available ore without badly damaging its availability whilst spelunking.

Additionally, after examining the heightmap, the 2.3.5 range chances to copper and tin risked reducing our three core mining bands to two, and have been contracted again slightly, sitting halfway between the 2.3.4 value and the 2.3.5 value.

Finally, Platinum was still too common! Especially Nether Platinum after the buff.
