Please, consider that your plant might be mislabeled? Your flower looks more like a Lyc cruenta than a Lyc macrobulbon.
Your description of the fragrance is also consistent with cruenta.
I bought it from Bush Orchids, who normally is really good with determining plants. I did think that macrobulbon flowers in spring, not in winter. So I was a bit sceptical as to what it is. But then cruenta does flower in spring too.
The colour is also a really deep canary yellow with an orange tinge. I am no Lycaste specialist. Any views are welcome ...
My first Lyc cruenta ('Nisqually' HCC/AOS), begins to flower every year around December. It has one bud already. I expect many more to develop in December and January into at least March. Yes, a larger number of cruenta flower in Spring however, a significant number flower during the months named above.

In any case: I must say I really like Lycaste. I got one as a present from a friend earlier this year, and loved it. So I had a get a few more ...
