The following exception is thrown while running uristmaps.bat in the usual fashion:

This appears to be the line throwing the exception.

The visited array uses the size variable for both it's "length" and "width", so if you have a rectangular shaped map (65 x 129) rather than a square one, it throws an index out of range exception because it either sets 65 for both the x and y index or vice-versa. This only seems to affect advanced world gen parameters when generating a world, not template ones, so making different height and width variables should help, instead of just one "size".
