I have a cave map I am preparing for my next game and have all the UDL set up, but when I log in with my 2nd player account I can walk through the walls.
This is my UDL setup (I used Shift-Click to place the lines so they are always connected)
This is my player view
And as the player (not logged in as the GM), I can move 2 squares to the left and pass through the wall
Here's the GM view of the same thing after the "player" moves
It is a very large map, could that be the issue?
