- Annan Chess: no more spurious en passant captures and duplicate castlings
- Marguerite: no more duplicate moves
- File Circe: Rex inclusive is now respected
- Intelligent mode: stalemate solutions where the white king moves to block a black pawn are found again
- Option MaxSolutions: is respected agian in hs stipulations

- effects are written with less redundancy
More elaborate handling of undecidable situations in carelessly specified fairy conditions
Removed Andernach grasshopper (is just a HurdleColourChanging Grasshopper)
