I have been having purge problems myself. I posted in dedicated servers but settings from my config for purge just disappear in particular the settings below.
On top of that I tried out the purge by using makemeadmin and then running the various console commands. I first had purge set to level 1 with the prep at 10 and duration at 30. I ran a startplayerpurge and got a purge but it was a single wave that died in seconds. no more waves came after 10 minutes of waiting. I tried a startNextWave command with no results.
I then moved the purge level up to 3 and the prep time down to 5 and didnt a startnextpurgephase after refilling out clan purge meter, we got a purge again it was one wave and then said they were regrouping with no other waves happening.
I had set the various duration from the settings server settings while logged into my server as an admin. we should have had a purge for 20-30 minutes but had 10 or less total enemies.
It also said black hand pirates I but we were attacked by skeletons. Not a single living person, only skeletons and some of those weird mutant hunch back things.
Purge seems to be seriously messed up. We are built on the shore in the jungle near the big pirate encampment so i dont see any reason pirates could not reach us. The enemies did spawn on the balcony of our base and not on the shore in front of it also, we are built against the side of a mountian
