If you are like me and purchased the True Tiles and did a lot of printing before the new upgrade to the openlock system, you may have pasted the original true tiles right on the openlock base provided. This creates a mismatch between the tile types in height, but allows the snapping of the two together.
I have the fix. I have a diagonal tile that steps between the two possible heights. From the Hero's Hoard link you can get the free sample pack. http://www.heroshoard.com/true-tiles which also provides the clip that is used for openlock using the 1 1/4 inch Wyloch tile sizes, also called True Tiles. The diagonal tile with the base and without are included.
The picture with the three tiles gapping to the base were taken on a curved surface and were not warped as it appears in the picture with all three.
Transition tile. I am not connected to true tile, but have just provided a solution to the transition between changes in the two types.
