killing bugs with fists doesn't count towards the lil fists mutation

[Kurtis Nelson]

punching and killing bugs with a bare hand is not counting towards the lil fist requirement counter, or is very inconsistent. I do have a buggie with me, but the buggie isn't interacting or fighting the bugs I punch, so they're not directly inhibiting the kill. i killed three gnats and it didn't contribute. is there something else I should be doing when trying to max out this mutation?

use the mitey claws works a little bit better

same thing happening to me with the bow mutations. Killed 10 different insects and didn't get any progress at all
