So, I have noticed that there's an issue with the !unbox system, where if you take out say a perma-pistol like a DL44 or a DC17S and you die with said pistol.
You need to wait a 12 - 24hr cooldown before you can pull either of those pistols out for usage again.
If this is a feature then obviously this post should be disregarded but I do hope it's not intentional.
