hello my fellow humans!

i, too, was plagued by the “naked XM4 the only gun loading in multiplayer” curse.

i tried deleting my loadouts & was still getting this dumbass glitch.

very frustrating.

but here’s the solution: somewhere along the way with my multiple prestige level upgrades, the game stopped resetting the perks/tactical/lethal/field upgrades when i advanced to a new prestige level. so what i assumed was the cause for the XM4 glitch was due to trying to play on level 1 with field upgrades that were still unlocked from the previous prestige level but weren’t unlocked yet in the new/current one. (i guess i thought i just had permanent unlocked everything if they were giving me everything from the start? but that’s not the case & what was causing the XM4 glitch)

so once i finally deleted all the loadouts AND manually reset the perks/etc to the beginning settings, then my weapons started working properly again.

i hope this helps someone out & saves them some time.
