I searched the wiki but there doesn't seem to be any mention of my particular topic. I somewhat un-commonly find zombies and skeletons with my EXACT gearset equipped. They have the same armor, and weapon that I do. I have confirmed this many times as I find mobs with jetpacks equipped, swords with knockback, and mismatched armor exactly the same as mine.

I havent died, these mobs are SPAWNING with my gear equipped.

I'm currently running a hybrid pack of both Unhinged and Unleashed.

I have every mod in Unhinged installed and these mods as well from Unleashed:

  • Adv Power Management
  • Adv Solar Panels
  • Biblio Craft Mods (all three)
  • Binnies Mods
  • Computer Craft
  • Damage Indicators
  • Equivalent Exchange 3
  • Extra Utilities
  • GraviSuite
  • Magic Bees
  • Misc Periphreals
  • ObsidiPlates
  • Plugins for Forestry
  • Soul Shards
  • ThaumCraft

I also installed:

  • Logistics Pipes
  • Infernal Mobs
  • Adv Machines

How often do you die? Zombies have the ability to pick up and equip items that are on the ground. If you die near them, then return for your stuff, they may be poised to use it against you.

If you're not dying often, then one of the mods must be adding this feature in. I know skeletons and zombies have been seen with high-end equipment like nanosuits, which appears to have been a Halloween prank included in the IndustrialCraft2 mod. The IC2 config file would probably be the first place I would look for an answer.
