Not that I know of. I have used Simcoe, Chinook and Centennial as well with no problems.
Not saying anyone isn't having issues. I stir mine each time I add an addition and that really seems to make a difference compared to when i didn't on the first two batches.
I think I have to stir more. Will stir more next time. Will update after next brew. Probably not for a bit. Vegas next week!! Party the following week. Then brew to restock after the party.
