using `set lexicon`, then loading a GCG does not keep the set lexicon

[domino14]

I really thought I'd solved the endgame algorithm even if it was slow. This endgame does not solve:

Best sequence has a spread difference of 57
Best sequence:
1) N6 FE
2) (Pass)
3) A6 L......
4) (Pass)

the correct sequence is EECHING/LEECHING/FLEECHING (with passes in between) for a total spread difference of 65

ARGH!!!!

[domino14]

Even with iterative deepening and alpha-beta pruning off it gives the same result. (Is the straight minimax algorithm buggy?)

[domino14]

This might actually be a set lexicon bug? The endgame tree does not seem to be generating any CSW-only plays (A6 EECHING#).

[domino14]

pretty sure this is not a bug anymore
