I built my purge base a few weeks ago and purges worked great. I tried to do some today and I am getting the same thing, There is no reachable location for the purge to setup their basecamp. I kept trying and eventually one would start, but after a few minutes they retreated and it ended. That happened a couple of times. I am on the ice by the Blackkeep and there is plenty of flatness nothing in the way. Like I said it worked great a few weeks ago. Purges would trigger on all three sides no issues, not at the same time, but one of the three sides when triggered. I have two gates with gate doors opposite sides of the base. I reduced it to one earlier and got that message and put it back in and still the same thing, so that wasn’t the issue.
