No warning or error, it rule name mistyped, just no output

What steps will reproduce the problem?
1. define IitoiAcc3 í -> i || .#. \%^* _ [ DCons | Cons  ] "^"  ?*  [ "+" 
{Acc} ]  ?*  ;
2. ...
3. define Grammar Lexicon .o.
                  IitoiAcd3;   # mistyped Acc as Acd

Foma loads things nicely, no warning or error,
but there is no output:
apply down> ég+Noun+Nom
???

It would be nicer, if foma gave a warning or error 
message in such cases. (mistyped rule names)
