Hivemaster items from Crystallized Supply Caches?

[Danikat.8537]

I'm trying to get the Crystallized Iron Gear, Crystallized Tadpole and Crystallized Training Whistle for the Hivemaster achievement. (I got the Crystallized Power Core sometime in the past.) I know they only drop from Supply Caches in their respective lanes but even focusing on those ones I've had no luck.

 

Do I need to be opening Supply Caches during the lane events, or is it just a very low drop rate?

Update: It looks like it has to be during the meta event. After getting nothing all evening I managed to get both the Tadpole and the Whistle during the meta (and both within 2-3 Caches opened) but didn't have time to try for the Gear as well. I'll have to make sure next time I do the meta I go down that lane.

Doesn't the Crystallized Iron Gear hint say "Can be found in crystallized supply caches in the SCAR lane"? Maybe it's just a matter of where not when, but it could be both.
