No bonus HK-47 drops for Cantina 12/10-12/-16 Event

Do you already have a 7* HK?

there is a bonus drop event on?

if so then guessing the OP just got unlucky drop rate tends to be low

Hopefully that doesn’t make a difference, and this is just a bug. That’s very rude to not give shards just because you’ve spent time energy and resources in upgrading the character already. That should be your reward for having done so.

I can’t believe you’re putting me in the position of defending CG, it makes me physically ill.  Typically they offer a different reward for players who already have the character maxed out like kyros, signal data etc.  In this case it’s just the shards themselves, it’s a catch up mechanism for people who need the shards.  Could they give them to people anyway?  Sure.  They aren’t though, it’s not rude or a bug just how they do things.  There are plenty of problems with this game, no need to go looking for more.
