Twilight Struggle FATAL ERROR THERE ARE NO CARDS IN THE DRAW

Hi guys,
At the begging of round 3 we got:

  • Discards shuffled back into Draw Pile.
    !!! FATAL ERROR: THERE ARE NO CARDS IN THE DRAW PILE!

and we now have 4 cards for USSR and 6 cards for US.
The Draw Deck is written 0 cards but I can see picture of more cards.
The picture of the Discards shows no cards.

Vassal 3.2.13 shown in Help menu. but in the main vassal window in the Twilight Struggle entry, Vassal version is 3.2.11
Twilight Struggle - 3.1.2

Thanks
