I also checked twice (today and yesterday) and it was at the 25th cleaning and posted about it. I only cleaned 30 times today (to check if I could still clean more buildings after collecting the blueprint) so I can also check in some hours time to see if it is possible to get more than 1 blueprint in 24 hours.
