Destructive Play keystone does not spawn bosses when witnessing tier 14 maps

Just did 3 maps in a row with destructive play and maven witnessing. Had just the map boss itself and thats it. Please fix it.

Bumping this. Seen this many times where only 1 boss spawns. Maven is definitely witnessing the map and still only getting 1 boss spawn of loot. Bosses that spawn multiple bosses will have piles of loot at each boss.

Need to test further if it's specific bosses or not but have to do 10 rotation to get back to test the bugged map and I'll forget which map it was or lack that map. Just did a Terrace with only the base boss spawn.

*edit* - Just finished a set and ran Terrace again, spawned 1 extra boss that time. So appears to be random trigger of 0-3 maybe instead of 1-3 additional.

Appears to be related to nuking the boss which I was doing off screen as a Sabo miner. Have to get into their range, let the bosses spawn, then start killing them. Ran like 20 maps today doing the slower strategy and bosses spawned every time.

Not sure if bug or intended, but definitely annoying with ghosted bosses.
