Ghost pieces?

I just played a game and all of a sudden  one of the adversay pieces becomes invisble! Ahahahah

I actually did not realize at first and was surprised when it became active and  I could not avoid the deciding move! But invisible pawns or other pieces is not the first time that becomes an issue for me!

DOE IT OCCUR ONLY TO ME OR CHESS.COME simply DOES NOT CARE?

Both things are possible.

It could be occurring only to you AND Chess.com does not care.

It may also be a trick of some players here .....ahaha

I find it funny! But a couple of times it has also  occured to me that all of a sudden i could not move strategical pieces, and lost while trying to move them!!! Amazing! Well , it goes whithout saying, I am talking   about bullet games!

Don't pieces re-appear in bughouse?

Sorry, I have no idea! I have never heard of this variant of the Game!

 Thanks for the advise notmtwain!
