Is the ex nihilo's sieve still bugged?

[Gysburi]

i'm using the latest version of mod tweaker (0.9.3) and the latest version of exnihilo (1.38.46)
if i use the format
mods.exnihilo.Sieve.addRecipe(input, output, chance); there aren't problems
but if i use
mods.exnihilo.Sieve.addRecipe(input, [array output], [array chance]);
it says
ERROR:\scripts\new.zs:93>a method avaible but none matches the parameters (minetweaker.item.IItemStack, any[],any[]);
and obviously it's impossible add multiple chance of drop for the same item or a multiple drop of the same item.
for example if i write:
mods.exnihilo.Sieve.addRecipe(minecraft:dirt, minecraft:wheat_seeds, 2);
or mods.exnihilo.Sieve.addRecipe(minecraft:dirt, minecraft:wheat_seeds*2, 2);
it says
WARNIG:[ModTweaker2]Overwritten 1 ExNihilo Hammer recipe outputs for minecraft:dirt
why "hammer recipe"?
