I was going over Plymoth Campeigne mission 10 in my head a couple seconds ago and I realised something rather odd. Sometime early on, you get a vortex east of your AL. Every time I've played the map, when the vortex appears, it would start heading towards the lab, and I would disable it. Once I disabled the lab, the vortex headed in the other direction. If I re-activated the lab, the vortex started heading back towards it. If I didn't the vortex didn't go near it again. Is this just some odd coincidence, or something coded into the mission?
Also, anyone else notice this, or is it only on my computers?
