First attempt at opening a bug, so please forgive me if I do this incorrectly. When attempting to make a goblin alchemist with the fire bomber archtype, bombs become resized to small, the extra bombs feat may not be taken. If the archtype is not taken, bombs stay at 1d6 damage and the extra bombs feat may be taken. Also, in the archtype, the bonus to hit due to the throw anything automatic feat is lost. The description of the fire bomber ability appears to say that the abilities of bomb and throw anything are modified by this archtype ability, not replaced.
"Fire Bombardier (Su or Ex): At 1st level, when a fire bomber throws a bomb that deals fire damage, all creatures in the splash radius take an additional point of damage per die of fire damage dealt. Fire bombers only add their Intelligence bonus to damage from bombs or alchemical substances that deal fire damage. This otherwise works like the alchemist's bomb and throw anything abilities. This ability alters bomb and throw anything."

Removed RESIZABLE from the bomb equipment object.
Added TYPE 'Bomb' to both original Alchemist Bomb Ability and the Goblin Bomb alteration ability.
Extra Bombs feat now checks for the Bomb type
Archetype does not remove/replace the Throw Anything ability, or the Alchemist Bomb ability.
