When playing six person cribbage, my hand was 4, 5, 6, 7, 7, 7; (no flush) which should score at 20 points; I got the following message:
1 fifteens for 2, 1 threes of a kind for 6 and 3 straights of 4 for 12 makes 23 points
Even if you add up the total from the computers explanation, it equals 20 not 23.

something similar happened with me too, which was reported through f4 back in then.

Hello,

Got it, nice catch! It will be fixed at next server reboot.

The problem occurrs for all hands where you have a triple straight of 4, where the three of a kind is at the beginning or end.
For example 4, 4, 4, 5, 6, 7 (counted as 29 instead of 26) or 4, 5, 6, 7, 7, 7 (counted as 23 instead of 20 as mentioned). When the three of a kind is in the middle like 4, 5, 5, 5, 6, 7, it is counted correctly (26 in this case).

Thank you for reporting !
