Examples: The Corrupted Village: The bucket of liquid cannot be picked up as an Iron Man Wrath of the Mummy: First room, if you misplace a gem and decide to retrieve it from the wall, you cannot pick up the gem. I can only imagine the amount of issues that Iron men will face in the future regarding this.... NOTE: This does not apply to items that passively spawn into the world. aka: The sand for sister city. I've noticed it's items that are spawned in and don't have a spawn animation. Anything that passively spawns into the world does this tiny upward movement before settling down and being able to be picked up. Items that don't appear into the world in this fashion are affected by code that prevents iron men from picking them up.
