Copying Loadout resets Heavy Weapon to default instead of copying

[zoffmode]

here's how my vehicles look in all my loadouts beforehand

 

then I do this

 

 

then it suddenly changes to Grattler here (maybe because that was the first Arch Gun I used Gravimag on)

 

 

so basically copying loadout doesn't copy Heavy Weapon and actually just resets it to default
