Just logged in to my server rented at g-portal after changing settings on number of players that have to be online in order for purge to happen. So after the server-restart required for changes to take place I find that all 7 doors in one of my houses have disappeared, while the neighbor houses still have the doors intact.
Repro steps:

  1. Build several houses
  2. Change server settings and restart server. (I changed purge settings for number of players online, first from 0 to 2, then from 2 to 1, bot with separate restart of server.)
