I made one that im not giving out the code for but its able to be played by anyone in the world with real betting and tons of features for the mod/admins

A bug found on total(hand)

if the hand is [9, "A", 9], the result should be 19 instead of 29.

Though I would not hit when I get a [9, "A"], but there is still a logical error in this situation

Actually ace and 9 is 20 not 19
