When two patterns are combined using merge style subtract, the result can tunnel down deep into the board far past the 0.8 depth limit. I found this in version 1.132 and now also in 1.133. This is not a serious problem and I am sure it is just a missed minus sign in the code! An easy fix if they just know about it. Attached is an example of the tunneling.
