OK, I found (and corrected) two problems in the Diagram script. When I added the possibility to include comments (enclosed in braces) in a pasted game some time ago, I had broken the reading of the shuffle specifier at the start of the game (which is also in braces). That was not the only problem, however: when the Diagram of a shuffle game is first shown, it displays as the 'nominal position', without any shuffling. But the initial value of the random seed used for shuffling (123456789) does not correspond to 'no shuffling'. But it was saved with the game. And if the game then was pasted back it was taken seriously, and the corresponding shuffle was executed. For now I solved this by suppressing shuffling if the random seed is 123456789.

I think this should solve all problems in the Diagram script. (Be sure to flush your browser cash or you would keep using the old script!) But there still is a problem with the games you posted: if I paste the 'alert' game into the Diagram on your alert page, it complains that Gi10 is an illegal move. And as far as I can tell, it indeed is one: G means Kangaroo there, which is defined as HFD, and  it starts (unshuffled) at h12. So Gi10 is an N jump. Since there is another Kangaroo on the board, and the specified destination square is illegal for both, it has no idea which of the two should move there, and throws up an 'ambiguous illegal move' error.
