Update: I asked QA to take a look at this and try to repro the bug. At worst, I’m going to try adding some additional UI to indicate where the enemies are located, in case the problem is that there’s an enemy somewhere that needs to be killed to spawn the next wave. (The initial spawns and story-specific attack waves look identical right now.) I can’t give an ETA on when this change will go in, but we’re not ignoring the issue, it’s just one that seems to have a very specific repro and I haven’t found it after dozens of play throughs.
