I'm using PT4 version 4.15.22 on a MacBook, and I just realized some hands we not tracked. For example, there is nothing between hand #---70 and #---72, but it is clear that there should be a HH there, as players' stacks are not the same between the end of #---70 and the beginning of #---72. This is not the only case where it appears; there are 100+ hands that disappeared.
What is going on ?
