As far as I can see all of the doors in Churberg are working correctly. Not all of the doors lead to an actual place yet though, such as the empty shops in Merchants Row. Caulderon seems to be working as well although only the gates have been populated so far.
The housing system should also be working. Most of the locked doors in Churberg are actually ownable housing. The next upload will have houses assigned in Caulderon.
If you find a door that isn't working please let me know where so I can look at it.
just posting asking what the status is for the recent bugs with the doors in the city and the housing system
