Bug report: Injector that has inherited the Artificer trait shows “triggered” text more than once.
In this situation, there was a lot going on. The screenshot includes the Reliquary modifiers in play, and these may have something to do with it. Or maybe it’s some lingering Artificer stuff…?
I recruited the Injector while the Artificer was in the lineup, so that buffing trait was inherited. What seemed to happen was that the trait triggered as intended for the first recruitment that occurred after the Injector was in the party, and the second time a new Follower was recruited, the flash animation appeared round the Injector, but I don’t think the +1 buff was applied (I think I had recruited that Sanctuary).
After that second trigger, I took a look at the Injector’s information and the second “(Triggered)” notification was there.

Sorry, I don’t do Discord or I would be posting notes like this on there. :)
