Error loading, says recipe iodine-from-seaweed has a textualID is empty.

Until the author fixes it: replace the line 366 which is in the iodine-from-seaweed recipe and looks like
{"",0}
with
--{"",0}

And replace line 421 which is in the water dump recipe and looks like
{{"",0}}
with
{{type="fluid", name="water", amount=1}}
(it doesn't actually matter what's in there, this recipe does not appear to be used anyway and could be commented out completely too - this one line causes the problem though so making it valid in any way solves the issue)

Fixed

the water dump thing was something i was trying to implement, the recipe of "iodine-from-seaweed" was intended to produces water as well, something like filtering the water, but i set aside the idea after spending too many time and not making the water dump work.
