I just started the game up and went for the third tech level in construction ... that's 5 techs I now have at max. Only the science has yet to be upgraded. Yet when I purchased the final tech level in construction I was awarded the Ivy League trophy for having researched all 6 techs (have attached a screenshot) ... I take it this is an error?

Anyway, thumbs up for a great game - may there be many more VV to come
