When crafting or modifying the "Whisper of the Worm" exotic heavy sniper rifle it is still located under the special ammo snipers tab in the enclave instead of a heavy sniper tab. This is obviously a simple thing but is definitely in the wrong place and has assuredly led to some confusion for many players when trying to find and craft it. They've added new sections to the heavy weapons tabs before (namely swords) I'm sure they're able to again for Whisper.
