still having issues with the following bug on ic2 1.09.113-if
"Summary 0000100: Quantum & Nanosuit are useless Description Quantum & Nanosuit do not protect from ANY damage (even from cactus), but Quantum Suit features working just fine (superjump, refilling Hunger etc.)
Armor is fully charged. Steps To Reproduce Equip Nano or Quantum Suit and try to damage yourself."
The bug says fixed, but it doesn't seem to be since zombies do anywhere from 2-3 hearts of damage with either a full set of quantum or nano armor. All the special properties of the armor work though such as fire retardant, falling damage, etc.
