They are.  That's a little confusing for someone accustomed to standard
paper-and-dice RPGs, where the same syntax has a different meaning (1d6 =
a uniform random integer from 1 to 6), and I was disappointed that it
can't do d20, let alone d100, because of bit field width limitations, but
at least it's documented.

Okay, here's a stack trace from loading crasher.g (as a regular game, not
in the designer) and then immediately selecting "save".  Made under Linux
on a PC, kernel 2.6.4, gcc 3.2.2, current XConq CVS version as of a couple
days ago.  The behaviour under the debugger was actually slightly
different from what I've observed without the debugger - namely, it just
gave me a segfault immediately without popping up error boxes in the GUI
first.

By the way, I removed the (set see-terrain-always false) line from my
actual game file and the save crash went away, just as in
crasher.g.  That's an okay work-around, I think, because the feature only
has minimal game importance.  The crash during play looks like it might
actually be a different bug, but it also seems to be linked to
see-terrain-always.
