Leave your purge base for some days active in the server without doing anything at all. Don’t add gold don’t change your thralls on cauldrons position.

(clearly speculation)
The server restarts for some reason read error and you cannot have a purge in this base.
When i restart on 8013 i made purge for two days, the third i couldn’t. So i left it be and did other things for about a week.

A couple days ago i started doing purges again and it was working flawless.
If your problem however is a bartender and you absolutely need one, i can work with a friend who knows how to do videos and send you a fast guide how to obtain a bartender really fast with really low material cost.
Or i can join your server just for a purge and then exit your call :+1:t6:.
