After crypto has been killed and respawned by allies (not revived), the champion banners that should show enemies in the area are bugged, both in drone view and in legend view; they no longer display the correct number of enemies, most revert to zero, and in the same set of 3 banners, each sometimes displays a different number.
It's misleading as you think you're walking into a safe area, and if you miss the audio queue (which seems correct, but harder to cross-verify), you're walking into enemies unaware.
