Naum 1.3 bug in UCI mode

Hi all,
there seems to be a bug in the latest Naum release 1.3. This bug only appears when the engine is run in the UCI mode though.
Whenever Naum's oppenent promotes a pawn, Naum will continue to play with the wrong colour. And doesn't take the oppenent's last move into account either...
Here's an example from a game between Naum 1.3 and SOS4:
Naum 1.3 vs. SOS4
After 100...c1=Q

abcdefgh8877665544332211abcdefgh(4/3) SMIRF FullChess FRC FEN-Editor (© by R. Scharnagl) Ver. 2.1.0

8/6k1/2N5/3K2P1/8/2R5/8/2q1r3 w - - 0 101
SOS4 just promoted the black pawn on c2 to a queen and now Naum's stunning answer is c2c1q too ???
The same happens in the following situation:
abcdefgh8877665544332211abcdefgh(2/2) SMIRF FullChess FRC FEN-Editor (© by R. Scharnagl) Ver. 2.1.0

7k/1P6/8/5n2/8/8/8/4K3 w - - 0 1
After b8=Q Naum will answer with b8=Q too...
Best wishes,
Martin
