WHY I CANNOT TRADE ITEMS WITH MY FRIENDS

[fygo47]

2//10 if i could trade with my buddy. we wanted to specialized 2 trees each and just trade. but it does not allow trade of weapons or armour.

not sure if this still works or not but build a weapon/armor crate in base put stuff in it shoot it till its destroyed and it will pop up at the discarded bag thing on ground if they havnt changed it since i tried it
