The old wood set was replaced in the update, but there has been a number of requests for the return of the original Wood set.
Anyone with the Wood set selected will now find the are viewing the "Wood Legacy" set from before the udpate. This looks poor at the largest size, and a higher resolution version will be created in future.
The new Wood set post update is now called "Wood Modern" and can be selected from the board style page.
