Added new Mutant building called Fire Resistance. It gives Mindblasters a fire resistance aura to nearby friendly units. It is stackable.
Made Acid Bomb research slower (90 secs instead of 45).
Reduced Karkino Acid Bomb damage from 30 to 25. Lowered range to be the same as Gunship.
Karkino Acid Bomb can now benefit from Artillery (Explosive) upgrades.
Amplicon uses Cannon upgrades (Concussive/Blunt) instead of Artillery (Explosive) upgrades.
Made some of the mutant research a little cheaper in terms of people cost. Some techs went from 20 to 15 people.
Roach Armor protects against concussive/blunt damage, not flame damage.
Reduced frequency of audio part of the "We are under attack" message. The minimap flare still is frequent.
Fixed three crash bugs, including a frequent crash bug that was introduced in the last patch
