So I noticed that after the patch that Either Custom Slot 3 and Custom Slot 4 when you set up Your loadout will usually not keep and give the Default AR and Pistol. Also your Gear does not seem to stay as well and ends ups not being there.
FT Loadouts PS4
This seems to happen if you are equipping the shader “Elite” to any of your weapons. After every match, your loadout reset, perks, gears, and weapons.
Same issue except only slot 3 retains gear and perks all other slots revert back to original load outs.
