Cosmic Anomaly doesn't spawn anomalies during combat

I’m playing a Barbarian with Cosmic Anomaly mapped to Upheaval. Anomalies spawn once every 5 seconds outside of combat, but they don’t spawn at all during combat. Not when I’m just waiting for them to spawn, not when I’m trying to get my over 40% lucky hit chance to proc on Upheaval, not when I use other skills to see if those happen to get the lucky hit procs. I get whatever I had before running into a fight, I can pop those, then I never see them again until the fight’s done. I don’t get any implosion procs so they’re not spawning and instantly blowing up either.

What is the Lucky Hit chance even supposed to do on this by the way? Is it supposed to give a chance when using the assigned ability to spawn an anomaly? If so, then why the hell would you call it a passive when it takes an active action with the same ability you use for its active to work to happen? Also, if it’s a lucky hit chance to spawn an anomaly, does that interact with the passive spawning of one every 5 seconds? Do those 2 scripts conflict, causing the game to take the lucky hit chance each time you use the ability and then go on cooldown for 5 seconds, potentially putting you in a state where you can never spawn them because the ability keeps putting itself on cooldown? Just remove the Lucky Hit part of the ability script if that’s the case. It’s breaking itself.
