Broken Bug Error!

Hello everyone, I don't know why it happened but this is what happened.

Long Story: One week ago I bought some crates to try and get the Royal Dragon Axe. I didn't get it but I received a micro gali scoped for 7 days... Anyway, I used the micro until it was fully damaged and it said in red writing, "Malfunctioning of weapon". Since I only had the gun for a week, I didn't bother repairing it, so I left it until the 7 days were up. After 7 days, it disapeared. I then opened up some of my zombie crates I had previously got 2 weeks before but I never opened them. When I opened 4 silver crates, I got the micro again but when I went to my Storage to equip it, I noticed that it was fully broken!

Short Story: Got micro gali from ZP crate for 7 days. Disappeared after 7 days. I opened Zombie crates and got another micro. Went to Storage and the micro was full broken when I just got it from the crate.
