Nebula gun skill “Nano Swarm” attacks non-enemies for 0 damage

[tropic agate]

As an example, in root earth there are beetles that are not enemies that do not attack running around on ground. They can be hit and killed with guns or melee. However when you use the nano swarm mod they will chase the beetles endlessly but not hurt them and so they chase and do nothing until they expire

[brisk arch]

For the little ground dudes, they seem to be unable to actually hit them due to the hitbox placement/sizing. However there are some enemies, like the pigs (?) in the burning man event in Losomn, which seem to be invincible, so the swarm gets stuck on them.
