I know this has been going on for a long time now. But why can't we lock doors anymore? Not complaining, just asking to see if I could get an answer.
In towns it would be a way around LWC chest locks or a way to hide from people in PvP, outside of towns players could just grief to enter anyway. It's pointless.
Just because it's pointless doesn't necessarily mean it needs to be taken out... but the hiding from PvP is the main reason it isn't implemented anymore.
