New content pack causing issues for people not using MMod

[X-Mezo-X]

Describe the bug
From what I've noticed, due to the content pack having assets from the MMod weapon pack, something related to the reloads of the MP7 and the AR2 tends to leave a permanent ERROR sign after reloading.

Steps to reproduce the behaviour:

1. Do not have the MMod pack installed.
2. Fire a few shots with either MP7 or AR2
3. Reload every few shots.
4. Boom a huge ERROR sign is now left permanently in your game session until you rejoin.

Expected behaviour
Reloading in MMod is reworked a bit, that's why this happens if you're not having the actual MMod weapon pack installed.

impulse version (press F1 in the bottom right):
This is more of a content pack error.

Additional context
I wouldn't recommend trying to put assets of MMod into a different content pack, it seems to be causing more problems (especially for those who do not want to use MMod due to how complex it looks like), not to mention the problem of firing sounds getting mixed up, as seen in both videos where the Full-auto gun sounds keep changing as you're firing, resulting in a bad impression coming from the firing sounds, also no reload sounds ever come from reloading the guns.
