In the sounds.xml file the main fire sound for the M60 is only half as loud as the other 7.62 guns, namely 54 iso 108.
Please see screenshot for clarification, no log provided as no ingame error occurs (works as intended, merely a wrong value).
On the crafting skills tab the tooltip for Armor states 'Boost loot odds by increasing any Attribute Levels'.
This is no longer the case since 2.0 as the Armor skills increase the loot odds of the Armored Up magazine.
