So I'm at the end of chapter one and fought and killed Alexander and his buddies, but the Drillworm hasn't spawned. I've run around the area, left to do more quests and come back, saved and reloaded, etc., and nothing works. I just can't move on in the story. To make it worse I'm on an Honour playthrough so I can't reload an earlier save before the fight or anything.
One other thing to note that I'm not sure is connected or not is that for a while there was something doing regular piercing damage and trying to knock down my character in the area where the Drillworm spawns. Every 10-15 seconds, the ladder nearby and my character would take about 126 damage directly to health and I'd get the message that knockdown was resisted by my physical armor. This would happen constantly, and it even happened during the fight, which made me run away and get out of combat to heal up so my character wouldn't be killed (maybe that had something to do with the worm not spawning?). Anyway, strangely enough, the last time I went back there before writing this, the damage and knockdown stopped. So I don't know what was going on with that either.
So, any ideas what's going on? Or is there a way to force the drillworm to spawn? I really don't want to have to start the entire playthrough over again. Thanks.
