"There is no reachable location for the purge to setup their basecamp."

[Skullys Corner]

I am new to Conan so please forgive me if this is a dumb question. I keep getting the message, "There is no reachable location for the purge to setup their basecamp." when I try to start a purge. I thought it was because of my location close to the big city in the west so I moved to open desert. Built a defense and again got this message. I moved a third time to the most open area I could find and yet still get this message. The Coffer is reachable thru many doors and a short maze. I have seen many on YouTube do it and I am taking pieces of all I watch and with no luck. Any help would be great, thank you.

"Through many doors and a short maze".

This sounds like a bit of a distance. How far are we talking here? More than a ten second walk?

One of the usual culprits is crowding too much treasure or defenses around the coffer. Try clearing everything within a 1 foundation distance of it in all directions. A single small treasure urn once blocked my purge from starting because it happened to be on the magic pixel the AI wanted to go to.

Another one that's gotten me was having two routes into the base, one of which was a side door only accessible by climbing. The Purge got obsessed with the door it couldn't reach instead of the wide open gate and cancelled the siege.

Keep it simple. One route in. Don't get too crazy with the defenses and silly mazes. You can launch tier 1 purges with a single sprinkle of gold dust so you have little to lose if the purge reaches your treasure, and then steadily add more defenses from there, testing each time. Then when the purge refuses to show up, you know it was specifically the last thing you added instead of playing a guessing game.

When they say no "reachable location" to setup the camp is not about the path to your base. It might help not to seclude it, but that error means there is no place to establish the camp that can be reasonably close to the camp.
If they determine they cant reach your treasure because it is too secure, the error says as much.

That being said, the way you have to face your "purge" is that you set a trap to bait them, so you are not protecting that as if it was your "life". You are giving a bait to attract the attack, which is kinda TRUE.
You dont make a convoluted high security vault if your intention is to attract raiders. You make it so they follow the path you want.
The obvious way to do that is making them funnel through one path that you prepare like what "my people" call "Polish Corridor". A single path open to the vault that works as a kill box.

If you try to make a convoluted path, your thrall losses will be higher, they will destroy more property IF they can get to it at all.

You are not playing "McDuck" there. You are attracting a raid, so you need to be raidable.

Otherwise, it would be stupid to "Proclaim Your Wealth", when you earn nothing else from it.

Same issue. I just built a single keep in a field with a portal where I knew they could spawn. The keep only holds my treasure. Its proving to be more defensible in the long run, and easier for me to keep track of my thralls there. Probably your best bet as well.

What is funny is that they themselves can make their camp in an "unreachable place" to us:
