Closed Weapons Playlist might be removed intentionally

I contacted support to see what is happening and this is what i got from them. 

response from suppot. 

requested to create a ticket for missing playlist.
"Okay but to set your expectations that may not receive an update for this because this isn't a bug or something. It's under developer decision and they may not disclose this due to internal info reasons. I hope you understand."

"Thank you for your patience. Upon checking, it seems that this will be on the developer side about that certain mode. I'm not sure when they're gonna bring it back. It's probably a rotational mode.

Maybe they intentionally removed it before the update.But they'll bring it back soon, though."
