A very minor issue:

Problems 12961, the four best moves have evaluations +5.64, +0.12, +0.09, and +0.12.  The last two moves are not presented in the order of the evaluation.  First problem I've seen that happen.  Of course the evaluations are so close it doesn't matter at all, but there might be a bug somewhere in the generator.

This is almost certainly the order toga outputs the moves in multi PV mode.  One of those moves is probably a "lowerbound" evaluation.  I don't handle this well in the generator. This example is fairly innocent , but is another example I've seen where the generator gets quite confused by this type of thing (lowerbound evals appear to be able to have toga outputting two lines with the same starting move in the 4 best moves which the generator REALLY doesn't like). I'll have to look at this for the next generator version.
