I have confirmed this is a bug. Thank you for bringing this to my attention, guys. The bug affects sims with seven cards specified where a hand has a range of hands for both the first two down cards and the final downcard.
Examples of affected hands:
(9-9-8)765*
5-4-K765*
Examples of unaffected hands
(7-7-)789J
9876JT*
235699T
I ran some statistical tests, and have confirmed that the distribution of hands is not correct. Blasted hand distributions! In a nutshell, for the affected hands, the last card is pairing more often than it should. I know how to fix the hand distro algorithm, now I just need to find time to do it.
I'll post here and on twitter when it's fixed. Sorry for the bad numbers - this kind of bug makes me physically ill.
