In the original game, you can bulk-buy a single stack of keys with shift+right click, which would either:
1: Refill an existing non-full key stack.
or
2: Buy a new full key stack.
Here’s what is going on in D2:R…
If the vendor is selling a stack with 2 keys, here’s how it pans out. Shift+right click:
1: 2 keys (first stack)
2: 12 keys (first stack)
3: 2 keys (second stack)
4: 12 keys (second stack)
…and so on.
Bump this one. Just noticed.
Cmon blizzard, we want ADDED QoLs, not removed them 
Reminder bump: While this a minor issue, it’s still an issue.
Thought: For the bug report forum, it’d be nice if there was some sort of indication that the bug report was “noticed” by a Blizzard rep and has possibly been passed onto the devs… Maybe an eyeball icon or something, similar to how if a Blizzard rep has posted in the thread, a Blizzard logo shows.
