There are several possible reasons for this. I've done some things which
use OBJ_create() fairly recently and I can't remember it being altered
since then.
You may be not using OBJ_create() properly: what arguments did you give
it?
Its possible you aren't using the ASN1 functions correctly.
To check this I suggest you write the object to a file then use
asn1parse on the file to see if you get the right "dotted" form of the
OID.
