Never has this happened

It's simple chemistry.

TA does not just disappear.

I don't know what happened, but what you are describing does not make any logical sense.

It's like if you put something in a safe and lock the door and then later check the safe and the thing you put in is gone, but you say that no one else had the key or combination.

Obviously, some part of the story is incorrect or something is happening that you are not aware of.
