It may have been because it defaulted to CWTN in the settings. I noticed this later, but I was already passed this step to test. When I noticed it, I believe it was in City of Mist and just stopped at the start, with Mercs still paused. I looked at the settings and CWTN was chosen. I changed it (hit save just in case) backed up a step and it was off to the races.
I thought I had set it to Mercs and saved it in at the beginning, but don't recall.
edit: Before I noticed the above, I was looking at the debug verbose and watching Rgmercs, and it was seeing the mobs, but it was OOR by being greater than the 300 camp.
