Don't know if intended but description states +6armour +10dmg, real effect is +2 armour +10dmg.
Same issue with zombie rotten flesh upgrade, in text there is mention of increasing all psychical resistance and fire weakness. That's not true it increases resists and simply don't change fire from what I observed.
Barbarian bloodlust upgrade mentions barbarians and war dogs is this typo and it should be tribesman and war dogs?
