Needing some help. I am on steam, and have White March installed. I cannot access Durgan's Battery, the world map says *Missing Maps 175*. I've gone through the area just prior to it (Longwatch Falls?), and tried to move on to the north, east, etc. But nothing lets me access the area Durgan's Battery.
FWIW, my party is all 13-14, and I've already killed Concelhaut (doubt it matters, but who knows). Please help me out. I performed an integrity check on my files in steam, no problems.
