Either I cannot reproduce it, or I don't understand what you mean. When I go to the Betza Sandbox, and assign the more compact description of the Lion Dog I gave below to the 'star piece', and play e12-e3 b2-b3 c2-c3 d2-d3 (all illegal, but just to set up a situation), I can then enter e3xd3xc3xb3, and I don't see any spurious highlighting or other irregular behavior. While there are still lot of pieces in range for the KADGH direct captures.
Are you sure you are not running a cached version of the old script?
