It's because now Mike can buy bigger staff pills in the drug store, and that increased the size.

Yes, there are some well known lag issues, and sometimes a bug stop you to progress to score with one of the girls, or the almost compulsive/grinding actions you should do every day to get more money or to gain attributes points; And don't forget that the wiki is not 100% accurate, and mostly of the time we don't read it, and we end screw up our playthrough for some quirk details.
(sigh) Anyway, I think this is part of the experience of playing LoSeSB, right?
