I tested every addon while disabling my other addons, and found multiple problems and balancing issues.

Errors:

Rifles:
[m9khd2_pony_foe_shambu_v1] lua/weapons/m9khd2_pony_foe_shambu_v1/shared.lua:119: attempt to call method 'Ignite' (a nil value)
1. unknown - lua/weapons/m9khd2_pony_foe_shambu_v1/shared.lua:119

Visual glitches:

Little mac / m9khd_pony_foe_little_macintosh_v1 has missing textures, floating bullets, and uses human hands for viewmodel. (I guess the hands was done on purpose?)
IF-18 / m9khd2_pony_foe_if-18_v1 turns purple, might be because of the cubemap on the model though
IF-88 / m9k_foe_if88 uses human hands for viewmodel
mc_m9khd2_pony_da_hyohunstandardblade_v1 is purple, might be because of the cubemap on the model

On some models, there seems to be a tiny floating AR2 in veiwmodels. (Mostly on melee weapons.)

Floating AR2 also found on the IF-18

How many shots/hits it takes to kill a player:

I appreciate all the hard work you've done, but almost every weapon killing in 1 hit makes anything other then Machine guns useless, and boring in all honesty.

Edit: forgot to mention every hit was done on the chest, as other parts do more/less damage.
