_______________________________________________________
Details:
In 1.9.9+svn, 51392M, when playing After the Storm 0.4.3, in The Triad part 3
[harm_unit] is used twice upon Galas. The second time that it is, a very low
negative number is floated upon him. Since this is not supposed to happen, I
placed this debug code before wml_actions.harm_unit:
function dump(t)
for k, v in pairs(t) do
print (k,v)
if type(v) == "table" then
dump(v)
end
end
end
and inside:
print(amount)
dump(att_stats)
dump(def_stats)
wml_actions.inspect {}
When [harm_unit] is first invoked, everything is fine; but the second time,
dump() returns this in the terminal:
1 -- that is the amount= value
slowed 0

0 0

The bug is that wesnoth.simulate_combat, under certain conditions, returns
*-nan*, that is not a valid WML or Lua value, but a C++ only value. Since I
have a savegame that always triggers this bug, I'm attaching it.
