UDL allowing player to walk through walls

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?

Tried this also in a game from the market place that I am only a player in (Against the Giants) and was able to walk through walls as well Move 1 square "north" right through a wall

On the page properties, make sure the "Dynamic Lighting Barriers Restrict Movement" checkbox is checked.

Well damn, I looked for that exact thing, but it is not on the DL tab but on the Page details tab.  That fixed it, thanks.

It's on the Page details since the same toggle also affects legacy. Doubtless when Legacy is finally put to bed, it will be moved to a more intuitive place.
