Spices or a newly developed allergy are the only options. I eat plenty of all of that without issue. I've had all of those ingredients in the past week as a matter of fact so I am guessing spice of some kind. I also ate flax meal as an egg replacement in the mix and that hasn't bothered me in the past either. I won't eat the Neat brand stuff again and I will test the flax out on my skin and tongue before I consume any more.
I've never seen lupin as a food ingredient here. That's assuming you mean a legume from the genus Lupinus and not a common name for something else that we call a different name. I don't generally have problems with any legume. Peas and beans are a large part of my diet. My primary protein source actually.
