That was the interior door problem which was reported yesterday, and I thought I had fixed in time. Fuck it then. Anyone who has lost an interior door's improvements due to relinquishing claim or losing a place due to late taxes, fix up the door again to where you think you had it, and then let me or another DM know how much gold you spent so you can be reimbursed - if you would still like/need that money. I'll take everyone's word on how much they spent.

This is from the server updates thread from awhile back. You need to get the lock DC up beyond a certain point, and after that there's a d100 roll to determine if Knock will unlock a door. So it sounds like you were getting unlucky with the rolls of the lower level mages.

-The Knock spell is no longer invincible over all locks. Now, if a lock DC is over a certain threshold, the Knock spell will do a d100 roll vs. the lock DC and, if the roll is lower than the DC, the spell will not be able to open it - at least for several in-game days. However, no matter how complex a lock, there is always at least a 10% chance the Knock spell can open it. The primary intention of this change is to make player houses much more secure (but not impregnable) if investments have been made to door locks, but also to increase the value of becoming a truly skilled rogue
