Multiplayer Pebbles bug

I somehow managed to invoke this state (pegs 1..4, correct position, wrong position):

_ _ _ _ 0 0
_ _ _ _ 0 0
_ _ _ _ 0 0
_ _ _ _ 0 0
_ _ _ _ 0 0
_ G G G 1 0
_ Y Y Y 0 0
_ O O O 0 0
_ R R R 1 0
_ _ _ _ 1 0

I had put W K P B (K = black) for the bot, BTW.

So, the first guess tells me that there's 1 blank peg. The second guess tells me that the blank peg is in position 1. The third guess, however, suddenly says that there's no blank peg.

Just happened again:

The second guess tells you that either the blank peg is in position 1 or there's 1 red peg in positions 2—4. The third guess rules out the blank peg on position 1, meaning it is in positions 2—4.

If the third guess meant that, then it would be "0 1" and not "0 0" though.

@erikkonstas , thank you for reporting the problem. We have investigated and fixed it.
