I remember this being an issue way way back when this was first released, but I guess it's still an issue? Once the capture target is, well, captured, enemies just stop spawning and so does the reactant. Meaning unless you unlocked your relic prior to capturing (which on some missions that's just not feasible) you won't be unlocking it this time around. Sorry kiddo. All jokes aside, can we please just make it so enemy mobs still spawn after the target is captured? It's not really helping anyone by stopping the flow of enemies before the mission ends. I feel like this should have been addressed already but maybe not
