When did they make this Flashbang change?

Previously, if you were carrying an item, then crafted a flashbang, the carried item would remain in your inventory, but you would be unable to use it until the flashbang was dropped or used.

Now however, it seems that once you craft a flashbang, any carried item will be removed from your inventory. Likewise, if you're carrying a flashbang, then attempt to pick up an item off the ground, it will replace your flashbang.

This change was not mentioned anywhere as far as I'm aware. Does this also include other limited items such as EMP's, First Aid Sprays and Flame Turrets?

Does anybody know if this change was intentional, or a glitch?
