That is in fact what I am doing, "Adding the Card to the Battlefield", but I've done this many other times with other cards that created tokens, specifically to test if the token image used was the correct one for the set played when new token images are added when a new set comes out.
I've never come across a situation when I did it this way that the token wasn't created after having cast the card that creates the token, so I guess in those cases, there was no ETB trigger associated with whichever card I was using to test for the token images.
However you state that the token is made when it's cast directly from the hand or using "Cast Spell/Play Land", so it is working under game conditions & I confirm this because it worked for me this way too when I chose to cast it using the "Cast Spell/Play Land" option.
Thanks for clarifying this for me, however I am still a bit confused as to why my original post about this "Bug" was reported fixed by you as I used the same "Add Card to Battlefield" option to cast the card that I assumed was the bug in question. I have to assume, maybe incorrectly, that you indeed found this bug, but not for the original reason that I thought was the cause for it.
